New foamer, help with pipe test
OK, I am new to Openfoam. I am trying to get a simple compressible turbulent pipe example working but am failing. I am trying to get english units working. I modified /etc/controlDict to english.
I run rhoSimpleFoam and I get about 5 iterations but the pressure at the inlet immediately rockets to like 1e6 levels. I can't understand what's wrong. any advice/recomendations would be appreciated. Am I missing something stupid? It's driving me crazy at this point. Some of the boundary conditions are below. k/omega are being set according to standard equations. Mach is around 0.1. inlet U type flowRateInletVelocity; flowRate 0.5; value uniform (0 0 130); P type zeroGradient; T type totalTemperature; T0 uniform 531.72; gamma 1.4; exit P type fixedValue; value uniform 2116.8; U type fluxCorrectedVelocity; value uniform (0 0 0); inletValue uniform (0 0 0); T type totalTemperature; T0 uniform 531.72; gamma 1.4; |
Check the mesh unit and make sure it is scaled in English unit

Mesh was create in pointwise in ft units. The points file is indeed in ft. Is there a mesh unit constant somewhere in openfoam?
