Hi,

When running an eddy current simulation in Ansys Maxwell 2D I encountered the following error message:

Solving for EddyCurrent adaptive pass 1, process solver2d error: Internal Solver Error:  'Can not multiply tensor with scalar!'. Please contact Ansys technical support.

The simulation is for a cross section of a coplanar stripline resonator to extract its inductance under AC drive. The substrate (sapphire) is implemented as an anisotropic dielectric as per the following paper: J. Krupka et al., Meas. Sci. Technol. 10, 387 (1999). The anisotropic model for this design has been used and found compatible in a number of other simulation software and solvers under Ansys (HFSS, Maxwell 2D electrostatics). Is there a reason why this is not working for Maxwell 2D eddy current? If not, is there a setting that I need to toggle that allows me to do this calculation?

Sincerely,

Chi Zhang

Hello Chi,

      Could you provide or show more informaiton on your model? like boundarie, excitation, geometry, etc. The eddy current solver should support anisotropic material.

Hi HDLI,

Boundary: Balloon

Excitation: Current

Geometry: coplanar stripline

Is there a channel through which I can upload the example Ansys file? This will be easier.
