Hello Joachim,
thank you once again for your help. Now I have created a simple python script to simulate such an inhomogeneous heat conductivity problem over time (see example_forum.py).
The example is about a brick element which is heated by a constant heat flow into the element.
However, I wonder about the solution which seems to be unphysical. If I choose the values
Code:
scal_x = 1
scal_y = 0.01 #1
scal_z = 0.1 #1
to account for direction dependent heat conductivity, I get temperatures (at intermediate points in time) which are below the initial temperature. This cannot be correct since the heat flow into the brick is always positive.
Do you have an answer to this issue?
Thank you very much!
Best,
Max
