'Fuel tank filling study' simulation project by Ali_Arafat


I created a new simulation project called 'Fuel tank filling study':

A Multi-phase flow simulation for filling of a vehicle fuel tank that is initially filled with Air. Originally done by dheiny.

More of my public projects can be found here.

Hi Ali

I have a quick question that I am hoping you can help me out with.

In the setup of this geometry, the inlet and outlet faces are separate faces from the walls.

How did you set this geometry up before importing it to SimScale in order to separate these faces?

I have a simple geometry that will operate in a similar manner, except that I also have a hole from which fluid will drain. I need to figure out how to isolate these the inlet and outlet holes in order to define the boundary conditions.

Any help would be excellent.

Kind regards,



please how did you assign the gravity vector


Hi @OKhaled!
