Hello I have a twin screw combustion chamber and for the bottom face i need to split them so that i can give different boundary condition to the different selection. It falls on the same plane and the best way in my eyes so far is if i can split the geometry into multiple equal blocks i can set the boundary condition differently.
Is there any way of doing this please?
I have attached the geometry snapshot and highligted the bottom plane/face to split.
Please if any one can help me out it will be highly appreciated.

Use slice, first make planes on where you want to split and slice on the planes

Hello thank you very much for the reply. I tried doing what you asked but for some reason i couldnt manage.. however i got an alternative route by drawing a line on the plane and using the project tool on the plane there by separating the plane in separate sections for selection.
I guess many ways to do same thing.
