As per the description I found here (https://www.openfoam.com/documentation/guides/latest/doc/guide-bcs-general-uniform-fixed-value.html), it is time. But I suppose for a steady state solver it...

This was the first time I saw a table entry in use so I didn't know what the entries meant but I found out and edited. The first number indicates the time not the iterations, I think. So...

Hi Daniel, I was pretty sure mesh was alright since this is the squareBend tutorial case just with 2x finer mesh. So the output of this is all OK: Create time Create polyMesh for time = 0...

I did have the simplest BC combination earlier - which included massflowrate (or velocity) at the inlet - it had not worked. Nevertheless, I did try this just now...

Hi Daniel, I made changes in fvSolution as you suggested but there's no change infact the time step continuity error increases. Starting time loop Time = 1 DILUPBiCGStab: Solving for...

Also, can simpleFoam be really used for such a case? I need the energy equation be solved. I think simpleFoam doesn't deal with T (energy equation).

I think I can do away with even pressure driven flow and a different solver but what I really am stuck with what BCs apply for T, especially if I want to...

Replies: 20 Correct BCs for known outlet conditions and unknown inlet conditions Views: 1,507 Posted By cfdcheckers Changing the geometry - modifying squareBend tutorial Ok, update. I decided to give up this case and try modifying the squareBend tutorial BCs instead. Again, am trying to have a pressure driven flow. So initially set the inlet to totalPressure and...
