Hi everybody, my name is Brendan and i am new to the flow simulation add-in from solidworks and i have run into some trouble. All the help is greatly appreciated as this is a part of my college finals.

I have desigened the stator and the impeller, the impeller has been fully enclosed in an non-merged cylinder. Since this is an impeller it is designed to "Rotate" and here is my problem, i can run the simulation no problem when the rotating region option in the wizard is turned off, i have a screenshot below of the result:

Here is a screenshot of the design:

For the rotating analysis the rotation is set to 20 rad/sec in the correct direction and the enclosing cylinder around the impeller is switched "off" in "component control".

when i run the simulation this time here is my result:

As you can see the water is not flowing throught he impeller!!!!! I can't understand it.

I have gravity also switched on and my reference axix is "x", im not sure if this have any error induced or not but any help is welcome.

 

Thanks everybody in advanced B.
