Hi @george-m, It looks like you have your gravity load curve flipped. It needs to be positive not negative, which I know seems backwards but it's j...

Welcome to the forum! So are you building your model yourself or using something previously made? If you are creating something, it will be easy to...

Hi @kein_roboter, Here's a good overview of damping: My suggestion is to first run your simulation without damping, so you can have a baseline...

Hi @okuyan, I'm not sure defining the brick as rigid is going to work for you. Try changing the brick to *Elastic material and look up some generic...

@kemoo it's difficult to tell whether the increased force is coming from the actual lattice structure being too stiff or from a factor in the boundary...

Hi @socra_89, I'm sure you solved it by now. What you did seems right to me as long as the death time occurred right before the birth time of the 2...

Hi @pauriera, Sorry for not getting this answered for you. You probably solved this by now but it sounds like you had issues with the Implicit conv...

@justintime98 Oh very cool, that's good to know. Let me know how it works with just the stress.

@ana @djsburra Did this ever get resolved?

I'm going to bump this because I've always wondered if there is a better way to do this as well. Anyone know?

@justintime98 hmm, so if you remove the *Include with the dynain file, then all of those *Initial_ files are no longer in the model correct? Just tryi...

@mrsmith glad to hear you got it worked out! Yeah sometimes certain material parameters act like switches for a material to change its core characteri...

@kemoo and your problem is that both of those contact forces are higher than the experimental data? Is it really noisy / are you filtering? If it’s do...

@kemoo do you have 2 separate surface to surface contacts for the top and bottom rigid plates?
