Hi! my name is Angel and I'm new to this forums, I came here because I'm struggling with SW Flow Simulation and can't seem to run it without any errors, I created all the necessary lids to completely close my control volume and there were no issues with that but after adding boundary conditions to all the lids and click run this message appears:

"It is not possible to calculate the internal task, if there are mass/volume flow openings but no pressure boundary conditions defined."

I don't know if I'm missing something, I just want to simulate a simple flow of water through the holes.

Here's a link of the assembly just in case you guys need it, maybe there's something wrong with the assembly but I think I've mated everything correctly:

Thanks!

Based off your error message, you have over defined your problem with an incorrect set of boundary conditions. You need to define an outlet (pressure outlet to likely get it to run.
