1034: Particle tracing feature gives unexpected results
The particle tracing feature in COMSOL Multiphysics sometimes gives unexpected results in Axial symmetry (2D) application modes. This problem is... -
1031: Flux through interior boundaries
When plotting the normal flux through the boundaries in my model, I am surprised to see that two adjacent boundary segments have opposed flux. This...

1030: Error message: "Out of memory"
The error message "Out of memory" occurs mostly on 32-bit platforms, due to the inherent limit in memory address space. We recommend a 64-bit...
- 1003: Plotting the mesh together with the solution How can I see both the mesh and the solution of my COMSOL Multiphysics model? The most straight-forward way to see the mesh of a COMSOL Multiphysics...
- 982: Axisymmetric plot swept to 3D How do I make a 3D plot from an axisymmetric 2D calculation? COMSOL Multiphysics 3.5 and 3.4 This is described in the COMSOL Multiphysics User's...
