Ansys static structure composite failure tool error

[jin-0917]

Hello. I am trying to perform a structural analysis of a carbon wheel using ANSYS ACP (Pre) and Static Structural. I referred to the built-in material properties of carbon prepreg in Engineering Data and modified them to input the material properties I intend to use. However, when I try to calculate the safety factor using the Composite Failure Tool, I receive the following error message.

The analysis for deformation and stress runs correctly, but errors keep occurring when calculating the safety factor. I would like to understand the cause of this issue. If there are essential material property values that must be input to calculate the safety factor, please let me know.

I tried to change the property of carbon prepreg if there was am missing property, but it was as same as the one that is in the Engineering data, but couldn't find an error.

Hi @jin-0917 , Thanks for opening the discussion. Please redirect your question to Ansys Developer Forum for Mechanical. There are many posts there that would help you since this is related to Mechanical scripting than PyMechanical.
