r/LSDYNA

Hello people,

I am stuck in a very worst condition in terms of my project, I was required to compute and interpreter a model in LS-DYNA but I am unable to do so as the interface of the software is so much difficult for me to understand, I don't have much time left for the submission and I am not understanding how to help myself. Please can someone guide me with it?

Currently I am working on crack propagation of NSCB model through Mohr coulomb. I have experimental data available with me, I just need to verify it by numerical analysis for which I am required to deal with this particular software.

Hello, I need to do a project for my degree with LS-Dyna, that consists in a impact test against the foam of a car head-retraint. I have the CAD created and the .k file also, but i have never used LS-Dyna and I also do not have the time required to learn it.

I think for someone with experience in this software it may be a really simple simulation, as i don't need any professional results, just a believable simulation, and it shouldn't take much time.

Of course if someone can help me i would be happy to pay something in reward. You can DM me if more details are needed

I am working on timber-concrete composites which fail in either shear or compression. I have gone through the DATABASE_EXTENT_BINARY for my materials. I can see the failure using the history variables, but the damage mode is still not clear as if it is shear or compression.

I want to learn more about it, because I think that I am unable to interpret the results of history variables.

Can someone suggest any informative source about the history variables in LS-Dyna other than the LS-Dyna manuals and dynasupport site?

I need to generate elements in the space between two top sections. I want to hide the smaller top section, rather hiding whole part, how can I do this?
