A question about magnetic fields + solid mechanics

Please login with a confirmed email address before reporting spam

Dear all

I am solving a simple problem with consol4.3a

it is so simple. A solenoid with current

I want to solve a stress by magnetic field.

Until magnetic analysis is everything is okay but after I add the solid mechanics.

I got this error

Failed to evaluate variable Jacobian.
- Variable: mod1.curlAx
- Geometry: 1
- Domain: 2

I do not thing, just add the physics

Please reply to me.

Best Regards

A poor guy

Hi

without a model it's very hard to say, perhaps you have some mix up with a variable name, COMSOl has many internal variables, adding a physics might rename one that you have already used and then the equations become bizzarre ;)

Good luck
