Initial strain error
I am trying to use an altered stress state of the material as initial condition for the analysis, I used the function INCLUDE with the dynain file, however i received warning 30183 shell strains inactive and 30136 solid strains inactive.
Does anybody know how to actually include these data in the initial condition of the simuation?
Hi @justintime98, this is my personal experience, but I believe you need to import the dynain file into a preprocessor like Primer which converts the altered state stresses into *Initial_stress cards, which you then save out to include in your 2nd simulation. I'm not sure if this is possible with LS-Prepost if that's what you are using. I feel like it should be though...
Here's an alternative approach too. I'm looking into if Prepost can do what you need though.
Also look into *inital_foam_ref_geometry. It's more restrictive in terms of what materials you can use, but you just input the initial nodal coordinates of all the parts you want preloaded and it will preload those parts.
