I have a long slot with small distances. So if I mesh this slot as a inlet boundary condition I get a very high number of elements. Is it possible to set this condition for example as a line inlet boundary condition or something like that? So that I can reduce the number of elements?
Best regardsMay 3, 2022 at 12:40 pmNikhil NaraleAnsys EmployeeHello,
For 3d case, you have to assign boundary conditions to the 2d faces. Having said that, you have to mesh the face and assign boundary condition to it.
However, you can play with the mesh and different sizing options if you want to reduce the number of elements.

I already thought that this will be not easy to solve...The surface should be a velocity inlet with a profile of measured velocities along the slot.
