Thanks, Lars! I got so excited watching and learning how to simulate the behavior of my 3D printed parts and then I heard you saying you cannot start the simulation locally. What a pity!

Just a timestamp I need to keep on going back (non-linear): 19:30 >> BUT I have a question, is it possible or does anyone know how to make wood as a material for simulation or is it always metal? When I open the non-linear study, the wood materials included (but can't be studied also..?) in static is gone altogether huhuhuh TT..TT or maybe a setting where I can change it to make more like wood maybe?

Am not an expert... however would it be possible to use the simulation engine with anisotropic materials (like 3d printed parts)? In particular, would it be possible to predict layer delamination? Thanks

That's a great point. It would be useful for certain engineered lumber as well like HDF.

Thanks Lars -- definitely subscribing! I wonder if it's possible to incorporate the strength of the screws into the study somehow. I understand that the fixed constraint assumes infinite holding power for the screws. I wonder if it would be possible to replace the fixed constraints with a force instead. Or perhaps we're talking about testing a complete assembly in this case.

Hi Lars, Once again thank you for this one. Yet another clearly explained video with the novice in mind. Your teaching style is great. Have you made any more tutorials on simulation beyond this one and the one before? It seems like a huge subject with a lot to learn. I'd really like to see something to help me learn how to set up a simulation to test for unbalanced loads. For example, I'm about to build a lumber store cart which will have to be quite narrow at the base and will have some tall sheets of wood stored upright in it. It's a simple enough design but I would like to run a quick simulation to see if it is going to be too unbalanced and topple over easily. Another thing I'd like to simulate and test would be turning circles as it will be on a set of rotating castors and needs to be wheeled away into and around a tight corner for storage and I want to make sure it can make it round. Also, is the simulation space where you would design and explore mechanics - things like links, pulleys, gears, clasps and suchlike or is it more just for material stress, thermal and acoustic dynamics type simulations? Is there a space for these other things or would you just use joints and constraints and push components around to explore mechanical dynamics? Maybe the Animation space has some part to play in this or is that really only for presenting your designs?

So it seems what I was hoping for in my last 3 paragraphs is not currently a feature of Fusion 360. I believe it is called rigid body dynamics. I just voted for it on the ideastation to be added down the line. Bend joints are also not present as I found out trying to make an assembly work that relies on springs to operate a catch system. One thing that can help a little when getting a sense of weight distribution and stability is the centre of mass command in the inspect panel. This displays the centre of mass for a group of bodies and appears to take into account their different materials. It appears to work with assemblies too but because the posts I saw that mentioned it were from when the feature was first introduced and it didn't work for assemblies at the time, I took a leaf out of your book from the model how you want Livestream and made everything bodies with a view to gauging the Centre of Mass whilst experimenting with the design then fixing the bodies rather than components issue later.

Hi Lars, Thank you for all the terrific tutorials. How many cloud credits did it take to solve the non-linear problem please? And, what does that cost?
@cadcamstuff
@cadcamstuff 6 жыл бұрын
Hi Vincent Barkley Thank you for watching! Non-linear cost 25 cloud credits. One cloud credit is about the same as $1. So about $25 to solve non-linear problems. Hope this is useful

Hi Lars. Thank you for tons of great material on Fusion 360. It was a great help when starting my venture into this software. I have come across some event simulation tutorials but my drop/crush tests generate bunch of failures. I couldn't find any relevant info in Autodesk page. Can you share some quick guidelines on how to perform a simulation of crushing object by free-falling heavy rick/etc? What initial settings and constraints should i set? My gravity simulation failed miserably, to the good laugh of my colleagues. Thanks!

Watched both the videos, and they were a nice start to Simulation study. I was hoping to simulate if a 3d printed housing would survive a drop. Assuming you added the impact force as a "load" to the component, is there a way to have it add the entire force at once instead of gradually over time? Thanks!

thanks but this would have been so much better if you had covered Contact Types. This bracket is perfectly-glued and has no bolt pre-tension. I got super-confused initially when I took this sim approach and found tension forces in the top of my (bolted to a wall and vertically loaded at the extremity) bracket instead of compressive forces at the bottom... because of the wrong contact-type.

No worries, I've learned a lot from your tutorials in the last week and really appreciate them. I reckon it'd be good if you had an advanced linear stress simulation video exploring all the constraint, load, contact and connector types, because I see a lot of people (like me!) tripping up with bad constraints, and they may or may not know enough to spot invalid results. In my specific case, I had a bracket similar your yours, bolted to a wall. It supports a vertical load but was showing all the stress in the top edge not the bottom edge, ie it was supported by infinite adhesion instead of bolt clamping force.

Hi Lars, thanks for the video When i want to put a frictionless constraint on the back side of the part, i only can select the whole part (7 faces) and not just the back side. I can not figure out what i'm doing wrong.
@code_racer
@code_racer 3 жыл бұрын
Try these 2 thinks: 1. Try first selecting the constraint, then on the window select the frictionless, then try selecting the back side of your part. If this doesn't work try this one: 2. Navigate with the cube on the upper side corner and press the back. then do the same as above. I hope this helps.

Hi Lars, is it possible in fusion to take two different constructions (like hollow beam and full beam) and preset it to have the same weight and run simulation on them to check which one is better?, basically i mean if i can set a weight to my component
@cadcamstuff
@cadcamstuff 6 жыл бұрын
Hi YANIV AMIR Thank you for watching! You can directly control your model by weight, but you can see the weight if you right-click the component and select Properties, so you could adjust it that way and then run simulation. Best, Lars

Hi Lars. I have noticed a failure of the stress simulation. Take for example the bracket with the reinforcement. when you apply the force, the force acts like a fluid and in the displacement view the both sides left and right of the reinforcement are displaced more. However, in real life this does not happen because the force is usually from a rigid body placed on the bracket and the bracket is displace uniformly, because if the both sides left and right of the reinforcement displace more, then the middle takes more force and eventually the displacement balances towards a uniformity, This of course makes me lose confidence in the program. Please comment.

Hi john antonas Thank you for watching! So I will not claim that I am a Simulation specialist, ever... :-) The simulation in Fusion is powered by the Nastran solvers that are pretty highly regarded in the industry....That is about how far I will go here :-) A better solution for both of us might be that you email me any specific concerns or comments and I will forward it to someone who is smarter on this topic than me...less nonsense you have to deal with lars.christensen@autodesk.com Have an awesome day!

john antonas I'm going to assume that getting the accuracy you desire will require doping the simulation as as assembly where you model the contact load as a component.
