Hi,

Does anyone know how to export the mtx file from Abaqus for a Tempreture-Displacement Coupled Element?

For either general displacement element or heat transfer element, I can export the elemental stiffness matrix by having an extra line in the keywords window: 

*File Format,Ascii
*Element Matrix Output,Elset=All,File Name=MATRIX,Frequency=50,Output File=User Defined,Stiffness=Yes

However, now I try to solve a Tempreture-Displacement Coupled problem and want to have both two matrixes (displacement stiffness matrix and heat conduction stiffness matrix) for each element, but the above output command couldn't work. 

Is there any way I can solve my problem?

Also, for the Tempreture-Displacement Coupled problem problem (steady state), will the temperature analysis affect displacement analysis (and how if it is)? Or do the two analysis conduct independently?

Cheers!
