Default Expression for Monitor point
Posts: n/a
Hi! I am doing simulation of axial flow Pump. During post analysis in cfx, I found that abbsolute pressure on the suction side is to much low in some area around the blade tip so it should create the problem of cavitation. Now i want how much volume or area around blade has pressure below some value say 85 kpa,this can be found in post through isovolume but how can I put in the form of expression i cfx pre to monitor it in cfx-solver. Thanks

You should be able to construct this using an additional variable. You could set an additional variable to be 1 if <85kPa and 0 if >85kPa then you calculate the volume integral of the additional variable and it will give you the volume <85kPa.
