MEMS Microcantilever with electrostatic actuation
Hi I'm new to Comsol and would like to model a mems electrostatic switch. For this I am referring to this example:www.comsol.com/showroom/gallery/444/ I was trying to understand the 3d model provided...
View ArticleInitially Stressed Bimorph Beam - Electrostatic Actuation
Dear All, I am attempting to model a bimorph which naturally deflects upwards due to stress in the lower layer of the beam. So far, this part has been successful. The top of the bimorph is silicon, and...
View ArticleHow can I calculate the electrostatic force in COMSOL ?
Dear All I want to calculate the electric energy between two parallel plates. One plate is fixed and another plate is moving along the Z-direction(moving 'up and down'). Therefore, the electric energy...
View ArticleQuestion about periodic boundary condition
Hello. I'm wondering what periodic boundary condition means. I mean, I have a geometry which has clear symmetric with respect to xy plane. I guess I really need to simulate just one of the half of the...
View ArticleParallel plate capacitor 2D vs 3D issue
I'm a beginner COMSOL user. I came across this problem while i'm doing some test simulations. I've simulated a parallel plate capacitor in both 3D and 2D. I wanted to see if I can extract the same...
View ArticleCalculate line to ground capacitance, 2D
Hello Everybody, I use COMSOL 4.3. And I use only the physic electrostatic (es). I want to calculate line to ground capacitance. The line has a length of L= 1 m. The conductor radius is r = 0.835 m....
