How to contour plot Tsai-Wu failure index for PSOLID MAT9OR in Hyperview ?

Theo Saclier

Hi everyone, 

I am working on modeling strength-anisotropy induced by Fused Deposition Modeling (FDM) and more precisely on implementing Tsai-Wu failure criterion. I have defined a MAT9ORT material with TSAI3D criterion (e.g. based on engineering strengths) associated to a PSOLID property. Moreover, I have requested for a FAILURE output in H3D format but when I open the result in HyperView the corresponding failure index is not available in the contour plot 'results type' tab. 

I have read other questions related to Tsai-Wu plot in HyperView and the solution for PSHELL was to go through the 'derived results' opening first the model. Is it still the only way to do it ? Does it work also for PSOLID element property ? 

Thank you in advance for the help.

Hi Theo

You may have found this already, but you need to use CFAILURE and not FAILURE to output the TSAI3D failure index to the H3D file.  This will work using a PSOLID with MAT9OR.
