Hi
I need a velocity BC that acts as an inlet and outlet. - for inflow: a specified mean flow rate with dynamically adjusting profile (like fixedMean) - for outflow: zeroGradient So it would be pretty similar to the pressureInletOutletVelocity BC, for which the mean inlet flow rate could be set. I want to use swak since the mean flow rate is determined from a different patch. Has anybody an idea how this could be set up in swak? cheers Fynn |

if you define:
valueExpression "0"; gradientExpression "0"; fractionExpression "(phi>0)?0:1"; it work as an inletOutlet, v*normal=phi, just change the value expression |
