How to add a Rotating frame in COMSOL?
I have been working on a MEMS gyroscope design and I want to add a rotating frame along with other physics interfaces for simulations.I have used COMSOL electromechanical interface(emi) for electrostatic actuation. So I want to... Read more »

Linear Buckling no eigenvalue found error
I've tried a simple buckling test. But an error occured -Feature: Eigenvalue Sover 1 (sol1/e1) No eigenvalues found. The simulation is a really simple one. - Just a cylinder(radius=0.03m , Height=1m) - Structural steel... Read more »

Drag Reduction
I'm a novice at COMSOL and am struggling to achieve this simulation. I'm attempting to essentially mimic the model of fluid flow past a sphere, but with air being released through "holes" along the edge of the sphere.... Read more »

Thin-Film mesh generation for Fluid-Structure Interaction and Electric Currents
Dear all, I am a begginer in COMSOL and I need some help in my model. I have a geometry that you can see in the attachments. The idea is to have a "cilium" that bends with a fluid and, in its base, a thin-film that will... Read more »

impedance of a porous-ceramic-like material
I am wondering which physical and study interfaces I may use to simulate the impedance of a porous-ceramic-like material. I am aware of the ESI and batteries module but they seem specifically thought for elecrochemical systems.... Read more »

Applying a sinusoidal pressure disturbance on a surface to get frequency sweep
Hi! I would like to apply a sinusoidal function to see the answer of the domain to such kind of excitation. Now I don't know if I am using the correct method. I use the maxop1 to find the pressure peaks and then I select a... Read more »
