MSC Nastran job dogbone_digimatcoupled completed.
This is the error I keep getting in Digimat RP's Input/Output Portal
*** USER FATAL MESSAGE 7836 (digi2nastranSOL400)
PLEASE CHECK DIGIMAT MODEL MATERIAL AND LOG FILES, SCA.MDSolver.Util.Digimat TERMINATED WITH RETURN CODE 2000
What is shown above are fatal error messages from the .f06 file for a tensile test whenever I try to run it on Digimat RP coupled wit Patran/Nastran via MSC Nastran/SOL400. The issue I have is that tensile tests terminate abnormally despite if I put constrains on the Parasolid. Note this issue only occurs when I use MSC Nastran/SOL400 and not MSC Nastran/SOL1XX with Digimat RP. The Digimat object is tensile test Parasolid imported from Patran as a .bdf file. This issue occurs whether I am using an elastic or elastoplastic material and whether or not I apply a constraint on the Parasolid in Patran. Can anyone help to resolve this issue?
I think this issue is coming from the output that you are requesting : Triax. This corresponds to the trixiality of the load. This output is not available with all material card, but only with a subset of them.
