update monitors obligatery for dynamic mesh
 

hi guys , my problem is to get the drag and lift coeffcient of a circular cylinder which is controlled by a synthetic jet so i have a part of the cylinder wich move sinusoidally due to an udf . i set this part as user defined function in the dynamic mesh setting . my question is when i run the calculation i get 2 figures of drag and lift which are completely different of those given when i run (preview meshing + update monitors) so the question is which set should i make is it run calcluation or preview meshing+update monitors ?
