Hello, I have three problems with units in Comsol. I am trying to simulate a MEMS device in Comsol. I prepared my 3D model in Inventor and I used "mm" as my unit. When I want to transfer my model to Comsol 4.1, before I transfer my model, should I change the unit to "mm" (w...
This change also modifies the scattering term in 2D when theScatteringtype is set toPolynomial anisotropicorHenyey–Greenstein; it will now be closer to the equivalent 3D model. This will not affect the results of models using theIsotropicorLinear Anisotropic Scatteringtype. ...
First: I think you have an issue with units and the location of the int1 function. The function is set up with mm and Comsol expects m in the constraint. Second: The x-axis is ranging 0 ... 100 mm, while your line in the geometry is located -50 ... +50 mm....
governed by the Landu–Lifshitz–Gilbert equations. We built a customized “Micromagnetics Module” using the Physics Builder in the COMSOL Multiphysics® software, which can be used to perform micromagnetic simulations within the framework of the COMSOL® software. This Micromagnetics Module can be ...
You can add aParametric Sweep, select any predefined parameter — such as the geometric size, material property, or frequency — and change its value through a specified range. As a result, you will get what are known asdispersion curves. You can even define cut-off conditions for different...

You can use the Cut Plane feature under Results > Data Sets to create such a planar surface. There is no need to go back and change the actual modeling geometry to insert this surface and solve the model again. This is a big advantage when you decide to visualize or compute some quantit...
