Time dependent Energy source ?

Post by TimoJT »

How could I define time dependent either heat to current source for transient simulation ?

I would like to test how electrical time dependent voltage waveform cause instant joule heating of structure and eventually what kind of mechanical stress this impact for same structure.
I guess chaining electrical, heat and elastic solvers would be needed. It is a bit difficult to find proper example to start with.

Hi,

say

Heat Source = Variable Time; Real 0 0; 1 10; 2 20; End

in the Body Force.
You can also use MATC or user defined functions instead of a table.
In ElmerGUI, only the part after the equality sign is needed.

HTH,

Matthias
