## Thermomechanical coupled simulation

Hi all,

I am trying to input a termperature field as initial conditions in
abaqus, to use the temperature distribution from a previous temperature
simulation in an mechanical simulation. But when I check the Temperature
values in the mechanical simulation i get great differences between the
nodal values (NT) and the element values (TEMP).

Does anybody know the reason of this problem?

Can it be related to the element typ? So the TEMP values are the avereged values from NT?

Kind regards!

## Temperatures updating in Abaqus (V)umat.

As we know, Abaqus/(v)umat provides the temperatures at each material point at the end of the increment, but in a thermo-mechanical problem, the heat induced by plastic deformation is unknown before the plastic strain is calculated. So, How the temperatures at material points in abaqus are updated?

Hi,

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

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!
