Voids Appear During Mesh Adaption

Hello.
Attached is a picture of cross sectional mesh and volume fraction contour. Mesh seems to be highly distorted and there are voids in some locations. What could be the reason for that? Note: I disabled the "mesh adaption" option under dynamic load balancing settings. Instead I'm repartitioning it at every 100 timesteps. Maybe that is somehow related. |

I guess you are considering 3d geometry. Since you took a section of the domain for visualising mesh adaption, the adapted mesh looks to be distorted. It's fine. Go for another section plane cut if you want to see your adapted mesh.
*The void in the adapted mesh is not the data loss or parallelization issue. It may be due to the cut-off of the selected variable magnitude beyond the chosen one in your contour plot. |

The void in mesh data, as you are mentioning, will not create any issues during the solution. There will not be any data loss in that void region. You can go on with that. I hope some other fellow may know the reason behind that. If you find out, please let me know or post in this thread later.
