I have been unsuccessfully trying to input orthotropic 2D thermal conductivities into the heat equation model.

I thought this was supported in Elmer based on the discussion of Model 1 - Heat Equation where it says that

*"For solids, conduction may be anisotropic and the conductivity a tensor"*

I followed the Tutorial 10 approach for an anisotropic Youngs modulus on page 50 to no avail. A result from one of my many attempts is given below:

Excerpt from the SIF file:

**Material 1**

Name = "solid"

Density = 1550

Heat Capacity = 1450

Heat Conductivity

size 2 2

real 0.1 0.6

0.6 0.1

end

End

Name = "solid"

Density = 1550

Heat Capacity = 1450

Heat Conductivity

size 2 2

real 0.1 0.6

0.6 0.1

end

End

Elmer tells me:

**Error:: Model Input:**

Error:: Model Input: Unknown specifier: [end]

Error:: Model Input: In Section: [material 1]

Error:: Model Input: For propert name: [0.6 0.1]

Error:: Model Input: Unknown specifier: [end]

Error:: Model Input: In Section: [material 1]

Error:: Model Input: For propert name: [0.6 0.1]

Is it possible to have solve a solids heat conduction problem with anisotropic thermal conductivity using Elmer?

If so, can you please explain how to do it?

thanks
