this time I am hitting with a fairly simple question - so simple that I cannot believe that it has not been asked and answered before. But one and a half hour of heating google's servers did not provide me any hints. So sorry if this is a dull question
I am trying to model an anisotropic material behaviour in thermal expansion for modeling an PC board, which expands more in direction of thickness than in lateral dimensions. I found actually the possibility to define the heat expansion coefficient in the SIF file as
Code: Select all
Heat expansion Coefficient(3) = 0.001 0.001 0.01
However, I would like to enter the material info the egmaterials.xml, but there the format is different:
Code: Select all
<parameter name="Heat expansion coeff." >3.43e-3</parameter>
and all guesses as to how it can be set separate for each axis have not been to Elmer's satisfaction... Can anyone give me a hint how to get this?
And if it is really possible, the next question that would torture me would be if the scheme
Code: Select all
Variable Temperature; 273.0 xxx.x; 323.0 yyy.y ; End
I appreciate your targeted feedback,
Thank you! Thomas.
