Expasion due to Heat

[Rich_B]

The load in the problem is a body force 'Temperature' keyword. I couldn't find that keyword in Elmer Models Manual in Heat Equation. I also couldn't find a test case using that keyword, but that may be just because looking through the tests for Temperature returns lot's of entries that are mostly inside Boundary Conditions.

Edit, in the Models Manual, not the Solver Manual

Changing just "linear system residual output = 1" and running shows that IterSolve gets to iteration 9 before NAN occurs. See the attached solver log.

I got the body force from the GUI
