how to get the DEP force

Hi everyone
How to get the DEP force in the particle tracing module?

I add the DEP force in the particle tracing module and than study it.

But the errors are as follows:
Failed to evaluate variable Jacobian.
- Variable: freq
- Geometry: 1
- Domain: 5
Failed to evaluate operator Jacobian.
- Operator: env_pgeom_fpt
- Geometry: Particles
Failed to evaluate operator Jacobian.
- Operator: env_pgeom_fpt
- Geometry: Particles


I get the electric field data from the RF module

Hi,

Did you get your result? Solved the Jacobian operator issue?
Please let me know, as am facing similar problem

Hi,
I guess the 'freq' is the built-in variable in COMSOL, so I added the parameter named 'freq' in 'global parameter' to replace the 'f0' which I used to indicate the frequency.
