Solutions - Boundary Conditions
- 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 interaction application modes. The result can be an incorrect heat flux...
- 1004: Resolving the Skin Depth
Why do the currents in my metal look strange? How can I get a realistic solution at high frequencies?
- 977: How do I turn an interior boundary into a perfect conductor in my In-Plane TM Waves model?
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 is available only for exterior boundaries. Why is this, and how can I...
- 942: How do I use coupling variables from the command line?
How do I use coupling variables from the command line, for example to make periodic boundary conditions or impose an integral constraint in a script file?
- 902: Thin film approximation, contact resistance
- 895: Can COMSOL Multiphysics handle left-handed materials?
Can COMSOL Multiphysics handle left-handed materials?
- 865: The inlet velocity is set as 4*Umax*s*(1-s). What does that mean?
The inlet velocity profile in the model library model "Flow Past a Cylinder" is set to 4*Umax*s*(1-s). What does that mean ?
- 850: Is there an 'open-boundary condition' for electrostatic or magnestatic simulations?
I want to simulate an electrostatic or a magnetostatic problem in free space. How should I set up my simulation domain, and what boundary condition should I use at the exterior boundaries?
