Boundary conditions

hello everyone.
I’m doing a rear wing simulation, and one of my teacher’s give me a guide to follow, in the bit of the boundary conditions he said “define the spoiler itself as a no-slip wall” but i cant select every faces, just some of them and the rest of them i cant because i just can select the meshed faces around. what do u suggest to do?


Generally speaking, running through some tutorials first is the best way to find out ways to interact with your model in SimScale.

For example, to achieve what you are looking for, you can simply hide faces from the enclosure and select the “hidden” spoiler faces. Figure 17 from this tutorial shows a workflow.

The box selection tool should also be very helpful here, to speed up the selection of faces.
