PotentialFoam Error

ocni · May 28, 2016, 06:14

Hey guys,

I'm trying to simulate a flow through some ducts in Sim-Flow. I'm new to this software and I keep getting this error: "Continuity error cannot be removed by adjusting the outflow. Please check the velocity boundary conditions and/or run potentialFoam to initialise the outflow."

My boundary conditions should be right and I use Potential Flow Initialization.
Does anyone have an idea to fix this?

Thanks!

PS. I tried to insert a picture of the error message. It doesn't seem to work. So here is a link http://imgur.com/usDHKU9

Hey Christian,

you said that your boundary conditions "should be right". How exactly did you set the BCs? Do you have an outlet?

Yes, I have an outlet defined as an outflow.

In both the pressure and velocity field?
