Hello.

I am trying to modify a case of Interfoam to include real world geometry with a constant inlet flow rate.

For a basis, I started with this case: https://www.youtube.com/watch?v=1zQbU-E4k1U

I am able to replicate the box to cell case for any configuration using a step file and Salome. However, I can not figure out how to set a constant inlet flow instead of box to cell. Here is an example of the constant flow I'm trying to create: https://www.youtube.com/watch?v=0K2QBjFS5VM

In addition to alpha.water, I would like for the simulation to show the velocity of the fluid.

Please let me know if I have left any relevant information out. This is my first time using the CFD forums.

My relevant code is below

);
}
);
