Hello erverybody, I have a question regarding Torque converter analysis. I have taken one sector from each of 3 components (Impeller, reactor &turbine). I have applied Inlet & Pressure boundary conditions at each component ends. And coupled these boundaries by regions. I tried to solve with explicit Multiple frames. For some reason it is giving Error #099. Please read following messege what I see every time I try to give a run.

*** ERROR #099 *** TANGENTIAL AREA > .005% FOR CELL 8960 FACE 2 TANGENTIAL AREA, TOTAL AREA, PERCENTAGE: -8.518357E-10 1.206000E-05 -7.063312E-03

It would be great, if someone could help me with this matter.

thanks

sham

In explicit multiple frames, the coupling boundaries should not have area component in the tangential direrction. In your case, it seems not too bad.

You can either correct your boundary mesh a little bit to make sure there is no tangential area or simply set Real Constant 68 to 1 to ignore the area check.

Thank you john it is working

hello sham!

i am just going to start the torque converter analysis using starcd. since i am a new user to star cd, could u able to help me the procedure how to proceed.

if u have any particular tutorials please reference me..
