Hello guys
I'm simulating a cantilever sensor, which contains three modules, 'laminar flow', 'electric currents', and 'particle tracing in fluid flow'.
For this, in electric currents module, AC voltages are applied, with frequency of 1kHz.
As dielectrophoretic force is needed, electric currents module is solved by frequency domain.
Laminar flow is solved by stationary solver, and particle tracing in fluid flow is coupled.
When I couple stationary(spf) - frequency domain(ec) - particle trajectories(fpt), it works well.
But when I couple stationary(spf) - frequency domain, perturbation(ec) - particle trajectories(fpt), it cannot be coupled with an error of 'complex number faces in real expression' like this.
Can you tell me why perturbation solver cannot be used?
