Subroutine simulation migration from HETVAL to UMATH

Submitted by PauloCalvo on Fri, 07/13/2012 - 11:15

Hi!

I'm already simulating a shape memory alloy behavior with the aid of the HETVAL subroutine, but I'd like to use UMATHT instead, since the HETVAL can't simulate correctly heat absortion(cooling down).

I've tried to add the required values for UMATHT without achieving a correct phase fraction simulation, and some times even no compilation of the .for file.

Is there any other examples that uses UMATHT besides the Stefan problem?

Any other recommendation about HETVAL to UMATHT migration?

Thanks in advance!

MATLAB for thermal simulation

I'm currently studying FEA/CFD and BEM for thermal simulation of custom dies within custom package mounted on custom PCB with encapsulate material (epoxy). I getting familar with CFD concept which seem overkill from ANSYS IcePack (too expensive) but exploring BEM technology from E3D in france (via Vishay).

I have access to MATLAB from other company to try it out for thermal modelling (BEM).

Heat flux per unit area due to frictional dissipation (ABAQUS)

Submitted by loizou2 on Thu, 07/23/2009 - 15:19

Transient Thermal Stresses

Hi all

I have a 2D model containing 2 2-D blocks rubbing on each other, producing heat at the interface. (Coupled temperature-displacement analysis in ABAQUS 6.8-1). This works fine, as the temperature on the contact surfaces in increasing.

Now, I want to get the instantaneous the heat flux per unit area due to frictional dissipation as a field output. Is there any standard subroutine or any other way to achieve that? There is no such a variable included in the standard ones.

Thanks!

Andreas
