Failed to Evaluate Variable Jacobian Error

Please login with a confirmed email address before reporting spam

Hello everyone!

I encounted this problem when I was trying to do a study(simulation) with Plasma module and Magnetic Fields Module in comsol. When I tried to include plasma domains to magnetic fields module, following error has happened. I attached my .mph file too!

The error message is following:

  • Feature: Time-Dependent Solver 1 (sol1/t1) Undefined variable.
    • Variable: comp1.mf.iomega
    • Geometry: geom1
    • Domains: 10-11, 13, 29, 32, 53 Failed to evaluate Jacobian of expression.
    • Expression: dvol_spatial(comp1.mf.dcomp1.mf.Jz) Failed to evaluate Jacobian of expression.
    • Expression: (comp1.mf.d(-comp1.mf.Hxcomp1.mf.testcurlAx-comp1.mf.Hycomp1.mf.testcurlAy-comp1.mf.Hzcomp1.mf.testcurlAz+comp1.mf.Jxvar(comp1.mf.Adepx,comp1.A)+comp1.mf.Jyvar(comp1.mf.Adepy,comp1.A)+comp1.mf.Jzvar(comp1.mf.Adepz,comp1.A)))(dvol_spatial)
