This very simple 2D transient model uses the Acoustic Module to show how a pressure wave propagates in time. The scenario is a simple 2D rectangle with one boundary acting as the source of the...

Solve a nonlinear PDE systems with Comsol 4.0. In this model, the PDE system is: du1/dt=d2u1/dx2 + d2u1/dy2+ d2u1/dz2-k*u1*u2 du2/dt=d2u2/dx2 + d2u2/dy2+ d2u2/dz2-k*u1*u2 with 3 spheres as 3...

This model is the electromagnetic part of the Loudspeaker Driver model (http://www.comsol.com/showroom/gallery/1369/). The acoustic module is NOT required to open this model.

This implemented Low-Re k-epsilon Comsol model is based on the Launder-Sharma damping functions as described in Wilcox's Turbulence modeling for CFD book. Model implementation was in 2D under...

CoBoGUI is a freely available collection of MATLAB scripts for two dimensional solar cell simulations with COMSOL Multiphysics and MATLAB. It proviedes a flexible graphical user interface and...

This model shows how to set up a SPICE model of a RCL-circuit in COMSOL4.0a with other initial conditions than default. The SPICE (Electric Circuit, "cir") in COMSOL does not allow you to...

This example show the electrostatic potential and electric fields in parallel plate capacitor with air gap. . Model by Michal Jedrzej Radziwon

This example show the electrostatic potential and electric fields in capacitor which plates are tilted and separated with air gap. . Model by Michal Jedrzej Radziwon

There are different boundary constraints in COMSOL structural, but in 2D/3D structural (smpn, smsld ...) there are no angular variables predefined, hence no easy way, as in the Euler beam modules,...

3D Euler Beam based FEM models calculate quickly and are very usefull for design otimisation and conctual design phases. In COMSOL, as most FEM codes, 3D Euler Beams require the input of quite...
