I want to simulate the magnetostrictive actuator hysteresis with Jiles atherton model. I modeled the actuator with comsol 5.0 version. The following error message appeared. What does it mean? How to resolve this error. I apply Terfenol-D properties also. GMA is modeled with Magnetic field, Solid mechanics and PDE physics.
Undefined variable.
- Variable: mod1.H1r
- Geometry: geom1
- Domain: 3
Failed to evaluate variable.
- Variable: Her
- Defined as: (mod1.H1r+(alpha*mod1.mf.Mr))
Failed to evaluate variable.
- Variable: normHe
- Defined as: sqrt(((Her^2)+(Hez^2)))
Failed to evaluate expression.
- Expression: ((normHe/a)<0.10000000000000001)
Failed to evaluate operator Jacobian.
- Operator: if
