Hello, thanks for the informative video. Do I need a copy of Ansys installed on the remote desktop/server as well to run RSM?

I am running a 2D transient simulation(VOF Fluent) in which vapor bubbles are generated at the bottom surface of a rectangular domain that is initially full of water with heat flux given at the bottom wall. I was trying to patch a single vapor bubble by creating a hemispherical region. I can see my volume fraction contour with the bubble after patching a hemispherical region at the bottom of the liquid. The simulation is also running perfectly when I click on "Run Calculation". When I do this same bubble patch operation through a DEFINE_INIT UDF, I can see the bubble getting patched in the vapor phase contour, but the calculation is not running. It is giving the following error in the 1st iteration itself. Divergence detected in AMG solver: vof-1 Divergence detected in AMG solver: x-momentum Divergence detected in AMG solver: y-momentum Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: temperature UDF code #include "udf.h" DEFINE_INIT (init2, domain1) { Message("solution initialised"); cell_t cell; Thread *cell_thread; Domain *subdomain; int phase_domain_index; //Initialisation of heater layer sub_domain_loop(subdomain, domain1, phase_domain_index) { if(DOMAIN_ID(subdomain) == 2) { thread_loop_c (cell_thread,subdomain) { begin_c_loop_all (cell,cell_thread) { real arr[ND_ND]; C_CENTROID(arr,cell,cell_thread); if (sqrt(ND_SUM(pow(arr[0],2),pow(arr[1],2), pow(arr[2],2)))<=0.00000002) { C_VOF (cell, cell_thread) = 0. ; C_P(cell, cell_thread)= 5846400; } else { C_VOF (cell, cell_thread) = 1. ; } } end_c_loop_all (cell,cell_thread); } } } } When I am running the calculation I am getting this error, but there is no error when I am patching it without udf by creating a region. I want this patching operation to be done via udf, so I can generate new bubbles after every time step in a specific pattern. (I will be using EXECUTE_AT_END for that ). I would be grateful if you can help me sir.

Why can't all tutorials be like this? Straight to the point, short, concise, awesome. Thank you!

very useful tutorial. How to assign port for a broadside coupled strip line and view their odd and even mode impedances in HFSS.

the linke plzz

😂

I am a final year Petroleum engineering student using ANSYS for my project to model slug flow/fluid flow through 90 degrees bend pipe (fluent). Please How do I setup wire mesh sensor and electrical capacitance tomography in fluent application or is supposed to be part of my geometry and if yes how go about that ?🙏🏾. I am at my wits end, I have tried everything I know but can't see the effects after simulation. Any guidance, directions or suggestions are warmly welcomed and appreciated 🙏🏾

Excellent. One thing i dont see is defining the contacts/connections between the fillet and the body.

"Not available for Polyhedral mesh" was a time saver, thank you :)

I see the mesh of the fillet is not conformal with the vertical and horizontal plate?

You F****** ROCK! For ages looking for how to do this!

I have a question. I am trying to build a similar model. Imagine your domain is split in half at that notch in the middle. One side of the domain will be stationary and the other side of the domain will be rotating around z axis. Although the periodic surfaces are still there, you have 2 of them which belong to the stationary fluid domain, and 2 belong to the rotating domain. Do you need to set up 2 separate periodic surfaces in fluent mesher? One matching the sides in stationary and one matching the sides in rotating domain. Or would it matter if you picked two surfaces from different domains and tag them with the same periodic surface? I am not sure if I was able to explain my question. In a nutshell, instead of 1 domain, I have 2. One rotating and one stationary. I would mesh it in workbench mesher but I am asked to use fluent mesher and I am not sure about it's capabilities

A second model could be developed, considering heating the plates before welding them and checking the final stresses after the slow cooling process of the entire joined piece. What do you think?

good work

Could you please share the equation in the field calculator with higher quality?

Is writing the 'report definition' out after the simulation possible? I have .dat files that could check the value, but I can not find a way to write it out.

I could save several hundreds hours if I watched this video three months ago. Thank you a lot!

Good video! Just one question: at the end of the video you didn't select "intrinsic" when you imported the curve (that seems a polarization curve and not a normal curve), Oversight? Thanks for the reply.

02:47, receiving error which generates a dump file without any details. Somehow, I can't gather original and inverse models in Workbench, where you have in system D.

Hi, I followed strickly the steps, but the resuling topology shape is not the same, it was removed more material. Do you solove the problem? Thanks

Does anyone know if the student version of Ansys will let you import GDS files? My student version crashes when I try to import GDS. This is an excellent simulation software.

The small offset was the key!!!, Thanks

Thank you for the demo. Is it possible to add the pivot feature? If IGVs are there which can be rotted about its pivot, then they are subjected to have leakage flow. In that case, it is important to model the pivot in the clearance and mesh it. Is it possible to mesh this feature in new turbogrid? Also, is it possible to mesh the cooling holes in turbogrid. Thank you.

such a great video!

How did you define the edge? Thanks for the video!

so, by change the topology to "merge", the big volume will automatically be split into 2 volumes, right? this is different from what I am struggling now

Can you give the temperature to the node? on the command ? Looking at your lecture, it seems like you can apply pressure to the node, but there is no temperature.

Well understood Sir. Thanks for sharing

how we can draw the graph between leakage inductance and thickness of the inductor

What is the procedure when you need to move several objets in one translation movement? I have the following error messge : " A wrapper object is required to contain all the moving objects in band for translation motion. The result will be wrong " Regards,

Thank you.I have a case like the situation in video，but needs to be applied an angular displacement.When I use the rotx command,its unit is rad or degree,and can APDL recognize the pi without any additional set?

Hi i dont know why but in my ansys if i click geometry i cant see the layered section option do u know why i cant access it ? thanks

hello sir, I sent to you an email for assistance, could you just confirm me that you received it well?

How to choose different surface under construction geometry?

I showed your video lecture for contact tool, and thank you very much. I have a question about a problem I have never experienced with the contact tool. When I insert a contact tool, a question mark appears in the upper left corner of the contact tool. Even if you try to delete it, it says that some paths to the contact tool cannot be found and it is not deleted. I would appreciate it if you could tell me what the cause is and possible ways to solve it. Thank you in advance

Great place for work environment

Thanks! Can you make a video on aeration flow in spillway by using LES and DES techniques

Great video thank you

Really informative video, thank you!

How did you create the geometry? pleaseee

Its because of videos like these that I'm subscribed. 😂

If anyone understand ,pls help me to define surface?

thanks for video, where can I fine some documentation for better understanding of what are harmonic indices

Great video, thanks... If you would like to take it one step ahead, import points into Excel, do a best fit curve, recreate points using the equation in a more uniform distribution. This prevents any non-uniform slope changes between any two points by creating a much smoother curve.

Big Help. You're awesome. Thank you.

Hi my question, I am using ANSYS 2023 R2. By using RSM can I design and pre-process job in Ansys mechanical while another job being solved in the Ansys solver?

How can you save this transformed mesh?

Hello. I'm curious about the process of defining a Fully Integrated Solid Mesh with SOLID 186. Do you have any videos or tips related to this?

Thanks a lot for the explanation. Can you post a screenshot of your temperature settings of the time dependent heat load (steady-state thermal b5 -> temperature)? That would be quite helpful!
