Hi,
I think he did two studies:
a stationary one with the electrostatics interface
and
a frequency sweep with the electric currents interface
In the first case, the capacitance is accessible directly.
In the second case, the capacitance can be computed using the admittance COMSOL gives you.
Is it ok to do the simulation with both the studies EC and ES in the same model.
And choosing the es simulation for capacitance and then choosing ec and running simulation again to see admittance ?
Is there any interaction between es and ec physics.
should this be run as two separate model files in that case ?
