I'm a beginner level COMSOL user and new to this forum. So please excuse me if I happen to ask a really silly question. I've been trying to simulate the behaviour of a piezoelectric crystal upon...
View ArticleAcoutics Module
I am trying to model a sound source (speaker, just a "power point source" now) in a sphere and prove that the sound is concetrated in the center of the sphere. Then I want to add sound treatment to the...
View ArticleInduction heating electromagnetic equation
Hi, i'm looking at the electromagnetic equation on the induction heating domain and I'm wondering about the terms multiplied by the potential vector. From which equations do they come? I attached a...
View ArticleHeat transfer_heating a nanoparticle
Hello guys I'm trying to get thermal distribution of nanorod(gold) which are placed inside the sphere(water). I designated nanorod as a heat source and simulate the heat distribution near nanoparticle...
View ArticleMass flow unsymetric matrix error
I am trying to do simulation of turbulent flow through a valve. I have a problem that the pressure variable seems to become unsymetric as soon as I have flow through the inlets of the valve. I am able...

Dear COMSOL users, The Early Bird Abstract Submission Deadline is getting closer! Do you have interesting modeling work that you would like to share with others? I'm curious to see what you have been...
View Article2D model coupling
I want to couple two 2D models, the first models computes a stationary state and the second should use the result to compute a time dependent model. I thought that with identity mapping I could read...
View ArticleSimulation of composite laminates
Hi all, Do you have any idea of modeling (simulation) of laminates , e.g. bi-layer composites having layers with different elastic modulus avoiding the so called 'free edge effect' (a stress...
View ArticleDoes Comsol support this type of modelling
Hello, I have had a look at tutorials, watched webinars, looked at models developed in Comsol, but I haven't found any model or reference to modelling situations similar to the following ones,...
