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... -
1021: Thermal turbulent wall functions give incorrect heat flux
In COMSOL Multiphysics 3.4 there is a problem with the thermal wall function boundary condition, which is available in the turbulent fluid-thermal...
- 1004: Resolving the Skin Depth Why do the currents in my metal look strange? How can I get a realistic solution at high frequencies? Not resolving the skin depth is one of the...
- 977: How do I turn an interior boundary into a perfect conductor in my... I am using the In-Plane TM Waves application mode in the RF Module. I would like to embed a perfect electric conductor, but this boundary condition...
