Excellent tutorial, smoothly show examples of crucial know hows in performing efficient FEA computation. A tutorial on the character of various contacts and their control, especially when plasticity occurs at contacts would be very appreciated.

Very good video tutorial on contact. Please post more tutorials on various examples, stress concentration, dynamic analysis

Great video. Much better than $$ training I've taken from ANSYS channel partner.

Thank you so much Dr.DalyO!! this helps a lot, thank you for the thoughtfulness to provide the models as well.

I would take time to appreciate the way you taught. A must watch video for the ones, who wishes to learn the Static Structural Analysis using Ansys, but can't find it easy to do. This video, takes you through all the basic concepts required for the Analysis and that too without over exaggeration, and by the end of the video, you realise that you have understood it and ready to go!!! Thank you so much Sir. Keep up the good work. 🔥🙏

Thank you buddy! Much better videos than those CAE worldwide videos that are so darn boring.

This is the best generic Ansys tutorial I've seen

thanks for the video. it helped me for solving bolted assembly problems in Ansys.

Best ANSYS tutorial video ever!!! really appreciate!!!

I am grateful for the video. It helped me a lot.

great video, please keep uploading more videos on Ansys workbench!!!

Simple, fun and super useful, thanks for sharing, you have one new follower

Great. Thanks once again.

Great video! Thanks so much.

Excellent tutorial

Beautiful video

Nice Tutorial, Keep on sharing.. Cheers!!

Good job man, thank you so much.

Great video man!

most clear explanation by the way.

thanks a lot for videos, quite helpful!

Thank you for this video, it has been very helpful!

Excellent presentation, thanks...

Thank you so much .... ! u explained amazing... i looking forward to see your other tutorial

VERY well demonstrated.

Amazing tutorial man! Thanks. You really master Ansys Mechanical. At 10:41, maybe if you add the displacement on both sides you get something closer to 0.3 mm. (Idk if you were already considering it)

Thank you so much man! It has been very useful for my work!

Thank you for the video, very well explained!!!

Thank You Very Much for DOWNLOAD LINK :)

Thanks for the tutorial. It helped me a lot! If you can explain why you chose a symmetric behavior for the contacts would be great. Thanks again for sharing this

Excellent!

great video! very easy to understand for a noob like me

excellent video

Very nicely explained. thank you very much.

You are a PRO

Thank you so much, this was so helpful :)

Thanks a lot for this video!!!

Thank you so much for helpful tutorial!

thanks for the video you helped my project really much

Nice... Very useful

thanks a lot!

wonderful!

Thanks for the video!! I'm learning a lot! Please, could you post more examples using Bolts pretension...?

Excellent presentation, Thank you

The guy is a legend

Thank you very much, it was so helpful

Excellent tutorial!!!!

Nice tutorial. Suggest some tips in ansys workbench.

Good video

Very useful video brother thank you now I studying in Glasgow Caledonian University and course work depends only on ansys

Thanks

very nice

i saw first time a native english guy teaching some ansys stuff

excellent and very informative video

THANK YOUUUUUUUUUUUUUUU

Great tutorial...Can I use the same concept for my model, which has an adhesive joint and a screwed joint, to check if the adhesive gives away as I tighten the screws? Also I would love to see how the reliability (time related failures) of a model can be simulated using ANSYS. Eg., If I were to simulate environmental Stress Cracking by putting the part in a humid oven, after how long the weakest member is going to crack. Good job!

Very helpful tutorial! Could you make some video tutorial for Ansys Icepak? Thanks!

Thank you so much for your tutorial video, this also guide me some suggestion in my work. But I still in my trouble. I have some case for static analysis. If there are 3 components. First, element 1 make element 2 deformation, then element 2 to contact with element 3 and transfer moment. All contact is frictional. I try some option in contact, but program didn't give me any suitable results

hey #DrDalyO , Thanks for sharing knowledgeable videos for us, Please add videos for Transient, spectrum and random analysis. Thanks in advance!!

waoh....whats a nice educative video.Please make a video on Transient thermal please please Thank you

+DrDalyO Thank you for this video. I am learning a LOT VERY quickly, so these videos are DEFINITELY helpful/useful. I did have one question though - you had mentioned that you can create a coordinate system and change the bolt pretension cross-section location. Can you please create and upload a video showing us how to do that. That would be greatly appreciated. Thank you.

Thank you for your videos....very helpful to me Sir, How can I apply prestress to a slab

excellent tutorial, could u please make tutorial about how to overcome convergence issues in multibody analysis, how to read the solver output, time, force criterion plots, thanks

Thanks alot . you are my jesus!!

Thanks bro make more videos

great video!! thank you so much!! can you do a tutorial about thread contact? with that function available with ansys 15 and latest?

Hi Doc, could you please go ahead and post a video on how to change the position of pretension on the bolt? Also, I'd really love to know what the symmetry/asymmetry in the contact area means, tnx by the way, the tutorials help alot. ;)

Great video! I am applying frictional contact, however loading perpendicular to the friction (bending). Can there be friction and keep the body fixed ?

Thank you for your videos sir, i'm really appreciated. Do you have any ansys video that is related to SMA(Shape Memory Alloy) properties or not? i'm so curious of how to apply these property in ansys.

Thank you for your video, let me know what is the difference between von Mises stress, contact stress and frictional stress

Thank you very much Dr.Dalyo. Very helpful tutorials. I wanna ask you I am modelling wall using masonry bricks and I want to add Interface connection (e.g INTER193 : 2-D 6-Node) between the faces of the brick. I don't want to use the automatic contact provided by the Ansys. If you have the command code I will be very thankful

Hello, thanks alot for this tutorial. I have just one question, for bolt pretension, you went for adjustmet but didn't explain what does it mean? like if i go for Load, does that mean torque applied on bolt, while we are fastening it?

hey man, how can i explain my thank to you? it's so meaningful for me (a self-learner) --- thanks million...

Great Tutorial! I have a problem of a beam supported on a concrete floor. This beam has no inertia to distribuit the nodal force equally along its lenght, and I want to know which area of the concrete floor that is supporting the load. How can I model it? Can you make a tutorial video regard this subject? Thanks.

very nice tutorial SIR. Was very helpful indeed i just have a small doubt. I need to design and evaluate a double skinned composite walls with shear studs. So can i do it in ansys or must i use any other software. If i can use ANSYS itself how can i start or proceed

DrDalyO: Hi. Thanks for your video. I have a scoping method problem with bolt pretension. when i select bolt area and click on apply, Ansys doesn't recognize that. My bolt is simply just like yours. Any advice?

Very nice videos!!! I have the following questions: 1. Let's say that you have some deform-able bodies and you need to connect through Rigids, How to we do that in ANSYS? 2. Is there any option to transfer the loads, say force or pressure on a surface through a contact surface without physically connecting it or is there any equivalent options. 3. can we plot shear force/ Bending moment diagrams on a 3D models; as in your 1st video on 3D beam.

hi, thanks for you video, usually the diameter of the hole in the bracket is slightly bigger than the bolt, so there is a gap between the two cylinder face, will this still be able add frictional contact?

Thanks for this video. I learned a lot. Can I supposed that the strutural material in this case is insufficient (210 MPA max) and i need increase/change for another, for example, material A516-Gr70 ? I think this, because on the curve the max tension is 500 MPA and the strutural material support only 210 MPA. It's correct ?

Hello Dr. DalyO. Am trying to model a prestressed concrete beam following your video in static structural "modelling of RC beam". I've modelled the beam, but how can I apply a prestressing force to the rebar using the same example.

how do we specify the compression only nature of the threads of the bolt, like the force transmitted between the threads of the bolt and the surface of the body to which bolt is connected?

Please teach more complicated geometries

Hello DrDalyo could you please tell me how to change the bolt pretension direction to another direction. I really want to know it.

Could you please show how we can obtain axial and tangential forces after solving the model? Regards, EA

Thanks for your tutorial they are really useful! Mesh question: Some guys (in DM) use in to divide model (slice material) in “regular” bodies and form with them a new part, in order to obtain a more regular mesh. For example consider our bolt and slice it in one minor diameter cylinder and one greater diameter cylinder: or our “C” bracket as a part made of 3 “body” plate. What do you think about it? it makes sense or maybe it is and old habit who comes by older or different program? Corner and edge question: Some guys use to delete fillet radius from model in order to obtain more regular mesh (like above) and reduce computational

Dear DrDalyO. At 8:44 You said very important thing about location of pretension cut. I have long bolt with pretty high pretension and I am getting large step in deformation of my bolt. Could You possibly provide any solution to get rid of this unrealistic deformation? Thank You for sharing knowledge.

Thanks, could you explain about trasient structural?, I want to learn this part of ansys.

Is it possible to use a beam in "connections" between two remote points and apply the bolt pretension to this beam and not to a geometrical object ?

Hi I am working with ansys aim and am having troubles with a multiphysics analysis. I have 2 plates that are bolted down and electrical current is run through the top plate with the bottom face of the second plate being grounded. I should expect to see and increase in temperature causing a structual change but all I get is an increase by .0008 degrees. I think there has to be something I haven't considered with the contact between the two plates and having additional resistance but I'm not quite sure. Any insight on this?

Hi DrDalyO, I followed your tutorial step by step but I couldn't get the contacts right. I'm using R16.2. I got question marks on the left of my frictional contacts. I got error messages saying "BONED or NO SEPARATION type required for this contact configuration". The error messages point to my question marked contacts. Any idea why it happens? BTW, really nice tutorial. Thanks! Steven

Hello, can you explain how to move the section that ansys applies the pretension?

i have a screw inserted into a bone, how to show the stress distribution in each part (nothing appeared in my results, just the colored force values)? also, the screw penetrated about 2mm inside the bone! how to prevent penetration? i used normal lagrange but the output results were wrong

Please let me know how to apply simple support to the half circular sold model, I faced this problem when I go to tool test, please kindly share how to apply simple support boundary conditions

HellO! If I have 100 bolts in different places, can I duplicate contacts and loads from one to others?

Greetings! Thanks you very much for your videos! It's all really helpfull. How do you think to make tutorial about construction made from beams and using the beam-element (line-body , i guess) to analize it? Or using different kind of elements in different cases and how to change it in WB. I think, it's the base knowledge and it will be really helpfull, espetially for beginners.

I am running a ansys anlysis with 114 bolts in the model. most of the bolts are contact with a cylindrical/curve surface. ansys give an error "The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please see the Troubleshooting section of the Help System for more information." Do you have any suggestion what I should do to solve the damn problem? Thank you very much in advance.

Very nice video, I have a question though: what if I need to evaluate the life? On the model I want to set some bolt pretensions and some external loads. Only the external loads should determine the cyclic load, while bolt pretensions should be a constant. How can I set this in the fatigue tool? Or maybe this is automatically done by the software? Thank you in advance

What type of contact should i use if one plate is grouted in foundation and second plate is bolted to the grouted plate. Second plate is a footing of a frame. Bolt is torqued. Could you please explain what contacts and boundary conditions should be applied? Thanks

Hello,, does this pretension tool treats the bolt as a tightened bolt with the nut ????
