Greetings,
I am currently trying to compute a volume electrical resistance. My volume geometry is relatively simple: a parallelepiped flanked by two trapezoids.
I would usually use ANSYS to solve this. I would fix a current at my volume edge and have the tension as a result. I would of course input the resistivity rho as a GLOBAL material properties.
My problem is that my resistivity is not global but is changing element by element. Moreover, it is not a scalar but a tensor.
For each node, I have a resistivity tensor.
Apparently, it seems impossible to input a local resistivity tensor (with diagonal terms) in ANSYS.
My input data are organized as such:
nodal coordinates | rho_xx | rho_yy | rho_zz | rho_xy | rho_yz | rho_xz
Does someone have any idea how to solve this problem?
Some of my colleagues are using COMSOL. Can it be done with COMSOL? I have heard that one can input their own equations.
