November 5, 2014, 10:26	2D butterfly valve dynamic simulation	#1
JackNJILL New Member AD Join Date: Nov 2014 Posts: 1 Rep Power: 0	Hello Friends, I am trying to simulate 2d butterfly valve using Six Degree of Freedom (SDOF) method in fluent. I am encountering error regarding negative cell volume. I have tried to optimize remeshing, smoothing parameters but its not helping. Also the udf is correct (to my knowledge) and zone motion preview is correct. I have used faceted setting for domain deformation, mesh used is unstructured. Any suggestion on how i can solve negative volume problem???
