Getting error while executing command to get image of velocity contour
 

I am working on this kind of geometry for udf to get rpm.After setting all the thing i moved to the "calculation activo-> execute command -> create -> define two command as image attachedAttachment 45133


Command1 :- /display/set/contoured/filled-contour/y /display/contour/velocity-magnitude..
Command 2 :- /display/hard-copy"velocity-%t.tif"

But i m getting error as attachedAttachment 45134
Tell me if command text is wrong and guide for solution.
Also tell how to make animation from that images

Your text and your picture don't show the same text.

In the picture, you typed "hard copy", in the text you typed "hard-copy".

What if i m getting negative cell volume detected in dynamic mesh?? Guide for a solution

If you're getting negative cell volumes with MDM then reduce the time step and/or increase the number of mesh updates per time step.
