Hey All
I am new into COMSOL and i hope you guys can help me.
I get this message when a try to run the calculation :
Undefined variable.
- Variable: pA
- Geometry: geom1
- Domain: 2
Failed to evaluate Jacobian of expression.
- Expression: comp1.mat3.def.rho
- Feature: Time-Dependent Solver 1 (sol1/t1)
Is there someone you can tell my how to solve it?
My project look like the plunger example at the model page : www.comsol.com/model/electromagnetic-plunger-36671
I have attached my project
Regards Benny

Define the pA as variable or parameters for atmospheric pressure of air at which the density of the air is calculated for the mass calculation.
