Multi variable dependent table material property

Hi all,

I am trying to import a table containing Magnetization values for Gd, based on the temperature T (K) and the magnetic induction B (T) for a magnetocaloric refrigeration simulation. However, I cannot find a way to import such a table with Comsol understanding to interpolate it for two variables.

Does anyone know a way to do this?

Any help is much appreciated!

Thank you Jeff! I figured out how to import the data from Excel into Comsol. Thanks for showing me the right section in the manual, it can be quite extensive sometimes.

However, I still have the feeling that the data is not really linked with the output variables (temperature ht.T, magnetic flux density mfnc.normB) of other parts of the model I am designing. I would like to be able to use customized magnetization values based on the temperature distribution and magnetic flux density field in the system. How can I link those?

Thank a lot in advance!
