UDF for outlet-vent pressure adaption
Hi,
following case: I do have 3 pressure-vent outlets. At the end I want to have a specific mass flow rate at each outlet (-+5%). If I use target mass flow rate my calculations crash (pressure is adapted every time step, right?) So I want somehow a function (UDF?) which check the mass flow after 1000 iterations. If it is within a limit its fine, if not the pressure should be adapted (lets say old_pressure - 1000) ... and this gain every 1000 iterations ... Can you help me with this? I had no experience with UDF so far and I just did it manually (stop after 1000 iterations, check mass flow, change pressure) ... Thanks |
