incompatibility between elements
incompatibility between elements
(OP)
Hello,
I'm using the "coupled temperature-displacement" procedure for creep with two kinds of elements :
-C3D10MT
-C3D4T (where the Von Mises stress is low) to reduce the computing time.
My problem is that Abaqus gives me this error message :"the selected geometry order will introduce an incompatibility between the selected region and the neighboring region", which appears in the Warning too.
What are the consequences of this incompatibility on my results ?
Generally speaking, are the incompatibilities between elements a real problem ??
Thank you !

I know that linear tetrahedron are really too stiff, however with quadratics like C3D10M I get good results (but the computing time is high). Besides, i read that for plasticity and contact, the modified tetrahedral (and triangular) elements are better to avoid shear and volumetric locking.
