impeller
 
Hi, i was wondering if anyone knows a udf that can be assigned to two impellers in motion. the impellers are both on the same shaft. the udf i am using is only allowing me the use of just one impeller (or sometimes the other!!). i am trying to fix the velocity profile on them.

Re: impeller
 
can you show me the schematic of your geometry and tell the motion you want to have? I will surely help you...

Re: impeller
 
thx for your rep. the tank is 11.5 by 10 m. the slurry level is upto 10.9m. there is a shaft of 0.2m at the middle, which consists of 2 impellers of 0.25m in width and each a total of 1ength of 1.4m.the distance bet the bottom impeller and the bottom of the tank is 3.5m. the distance bet the two impellers id 4.2m. i am trying to do a 2d simulation.
