anisotropic thermal conductivity

HI 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&...

Re: Heat conduction & Material Principal Directions 3/16/10

HI Peter

I can do that. I apologize for my laziness in asking this question.

Can the conductivity tensor be defined as temperature dependent? The Elmer tensor examples I have found show the parameters as constants.

Thanks for your quick response and long dedication to Elmer!

Heat conduction & Material Principal Directions 3/16/10

Hi I need to model an orthotropic material for a heat conduction problem. The material principal directions are not aligned with the model coordinate system in my problem. The Linear Elasticity model allows rotation of the elasticity tensor, but the Heat Equation model does not have a similar menu i...
