RE: No stresses in post processing

@usama-yes4 Do you know if you can load stresses or strains through the ascii file to plot? That may help determine if the problem is only in the frin...

RE: No stresses in post processing

Hi @usama-yes4 Try adding *Database_extent_binary and making the flag STRFLG=1.

RE: Can a shared node have different value when probed while postprocessing?

@shrikant_panchal No if a single node is shared by two elements the node cannot have two separate motions. The motion of the simulation is the nodes ...

RE: Strain under the local CS

@lon Oh perfect! How were able to figure it out? I believe that this is something that many people have been curious about.

RE: Stuck on flush i/o buffers

@saberman12 I would do an element quality check to make sure that you don’t have any really small elements somewhere in your model. Really small eleme...

RE: Strain under the local CS

@lon I’m pretty sure you need an anisotropic material and then there is a flag to activate in the material card that should allow you to look at local...

RE: Erode contacts removing elements before contact is made

@groll And you want the fluid elements to erode when they impact the wall? Why don't you try an SPH simulation? That seems more reasonable for what yo...

RE: Erode contacts removing elements before contact is made

@groll What exactly are you trying to simulate? Is this a fluid hitting a wall?

RE: Erode contacts removing elements before contact is made

@groll What are you trying to replicate specifically? Do you just want the elements to erode when they contact the plate? The issue you are probably h...

RE: The error of LS-DYNA cutting simulation

@takaishi This seems to be an issue with a couple people here. There was a topic a while back by @erick and I’m not sure if he ever got it figured out...

RE: Shear Stress continuity in layered composites

@fabian I’m not 100% positive how to export stress in the local coordinate system of the element, but I’m pretty sure it depends on the material model...

RE: Shear Stress continuity in layered composites

@fabian Gotcha. Do you know that the shear stress does in fact transfer to the polycarbonate experimentally? It may just be due to the differences in ...
