CSV file import to creat a new non linear material in SIMSOLID

JiCi

I’m having trouble importing a CSV file to define a nonlinear material in SimSolid.
The file is a valid CSV and starts with stress, strain, but SimSolid does not recognize it.
I’ve spent several hours trying to import what should be a very simple file. Unfortunately, none of the provided examples work for me, and the SimSolid documentation does not clearly explain the correct format or workflow for this case.
At this point, the lack of clear guidance and reliable examples makes it extremely frustrating to use SimSolid for nonlinear materials, as a basic operation like importing a stress–strain curve should not be this difficult.

Hi JiCi,

I understand your frustration importing a stress–strain curve via CSV in SimSolid can be tricky because the software is very particular about the file format. The CSV must start with a single header line, for example Strain,Stress, with no extra spaces or special characters, followed only by numeric values. I am attaching an example file for your reference. It follows the correct CSV format for SimSolid: the first line is a header (Strain,Stress), and the following lines contain only numeric values, starting at zero strain, with no extra spaces or units. You can use this as a template and replace the numbers with your own stress–strain data.
