SimScale says I don't have boundaries, but I do. I think

Using SimScale Fluid Flow / CFD

Sorry if this is just because of me being silly, I’m a total noob to CFD sim.

I am following this tutorial:

for the auxiliary fan duct of my voron v0.2 and am getting this error message:

“The simulation does not contain at least one pressure boundary condition, which will lead to global continuity errors. Mass balance will be difficult to enforce and the run will likely fail. Please use at least one pressure boundary condition (outlet or inlet).”

However, I have defined an inlet and outlet. Did I do it wrong?

You should be able to see the public project on my profile called “V0-Aux-Fan-7530”

Thank you for your help,

Alex

lol I figured it out. I used a velocity outlet instead of pressure. Sorry :slight_smile:
