Unclear warning in SOL601/106

Hi,

 

short question to all experts :

 

Why do I get the following warning when solving nonlinear solution 601-106 with ATS at the beginning in f06 file?

 

***WARNING: Large strain kinematic formulation is not applicable with material ** for PID **

 

I use MAT1, MATS1 and TABLES1 declaration and standard PSOLID parameter for parabolic Hexahedron eLements.

Why do I get that warning?

Does my solution consider large strain assumptions? I do not know if this warning is realistic or not.

Does my definition parameters point out that my material declaration is not suitable for large strain kinematics?

 

As results I get nonlinear stresses and strains and therefore I believe solution is correct. But what does the warning mean?

 

Any suggestion will help. With best regards,

Michael
