Default How to define momentum source?
Posts: n/a
In CFX build 5.5 I want to define linear resistance coefficient. In which direction (u, v, or w) of the velocity will it take effect? Because the Help says the linear (or quadratic) resistence coefficients are related to the x, y or z components but in the source definition window of Build I can define by components only the momentum source, for the coefficients there's no option to define which velocity component I want to handle

It's isotropic resistance in all three directions. You can't currently specifically do x, y or z independently.

If you want to define an anisotropic resistance coefficient, you can use the momentum source term with an adequate CEL expression for linear or quadratic source term.
