Hello sir,
I am working on the design of " comb capacitive accelerometer".
How do I give a sinusoidal actuation, before evaluating the simulation?
Thank you

Hi
check your doc and the FORUM (try a search), normally for time dependent solvers you define a load or driving voltage as V0*sin(2*pi*f*t) where f is the frequency and t the time in seconds, and V0 the amplitude. But you can also solve in frequency sweep / harmonic mode.,Then it's a AC steady state response, in which case you define V0 the amplitude and set the excitation frequency in the Solver frequency entry (possibly you add a phase with a phasor expression see the doc)

Good luck
