Dear friends,

I am simulating conduction heat transfer in a block whose thermal conductivity is different in three directions.

In fact, the directions are totally different from the global reference frame directions. So, I have to go through "Anisotropic Conduction".

The problem is that when I change the direction of the body (in this case the directions of conductivity is alongside the global ones) and I use orthogonal conductivity, my results are a bit different (around 1 degree Celsius) compared with the condition in which I use Anisotropic Conduction.

What could be the reason?

Any idea is appreciated deeply.
