Hi,
I have a mesh with an outlet and an inlet. Iam calculating an compressible case and its very important that both massflows of the inlet and outlet are equal, so i have a target massflow at the inlet. I have for U: inlet with a flowRateInletVelocity; outlet with zeroGRadient; for p: inlet zeroGradient; outlet type groovyBC; valueExpression "SOME CALCULATION"; value 100000; So i want that p for the outlet is calculated by groovyBC, but when i start the calculation after 3 timesteps i get a bounding problem bounding (Cp|(Cv*psi)), min: -8.08392e+08 max: 1.352e+07 average: -316717 So what can i do that both massflow a going to be equal after some iterations??? |
