I have added an internal fan with constant flow, but I have an error:
Warning Comment:Mass Flow is out of Fan curve's range Condition name : Internal Fan 1
I tryied to raise to a very high range pressure but did not help:
I saw a similar post, but seems not working here.
any idea?
Use a volumetric flow rate boundary condition, not a fan.
Internal fans need a fan curve, at the very least you need a maximum flow rate and a stall pressure point.
the question is I Need a closed Loop, (like similar post here in Forum) , if I apply a boundary in and out will not work, because also it is not optional to set the temperature of the flow. the flow temperature might increase with every recicling in the model.
OK, so find out what your fan curve is (the manufacturer should provide this information) and then use it with the internal fan feature. If you cannot find a suitable fan, then you need to just make an educated guess about the stall pressure, but make sure you set the flow rate to '0' for that point.
I Need a specific flow. the fan is controlled until it has the specified volume flow.fan curve is not relevant in this case.
I will try with two boundary conditions (one with flow in, and one out)connected with a temperature condition.
