MATUSR, MAT4 in weakly-coupled solution

Hi everyone,

 

I am trying to run a weakly-coupled solution (thermal and structural) with a custom MATUSR subroutine.

 

If I define the properties using MAT1 and MAT4, it works perfectly fine (see the attached model brick_coupled_builtin.fem).

 

If I define the properties using MATUSR and MAT4, I receive the following error:

*** ERROR #  70 ***   Thermal loads exist, and all material thermal expansion coefficients are zero.

 

I did not see anywhere in the documentation whether MATUSR did or did not support extra material cards. Would you have any idea if that's possible?

 

Thanks,

Cédric
