I am modeling a transient discharge through a flowing fluid in a nozzle. one of the electrode is moving so i created a sliding moving mesh for the movement by creating an assembly resulting a continuity boundary between the moving domain and the rest of the model. thus i had to add a continuity BC for the fluid flow ( hmnf ) . everything works fine but i am really disappointed by the results as in the attached images.
( In the attachment as you can see, an image of power dissipation and electric field. )
the continuity BC seems to effect the flow however i fine the meshing !! i also used automatic re-meshing but results still the same !! Extremely fine mesh for boundaries even for the near domains didn't work better !
weak constraints for the continuity gives an error in the hmnf interface !
Any help would be really appreciated .
