Problem with Solid (Divemesh)

NiMinic · June 17, 2021, 07:55

Hi, I'm Nino and i'm using REEF3D. I have some problems with solid generated with the Dimemesh options, particularly with the ogee weir, because when I do the contour of the phi level the water flows through the solid. Does anyone have the same problem or a solution? Thanks
Best regards
Nino

can you upload an image with the described condition?

Hi, thanks for the reply. This is the actual situation. I'm forwarding you also the ctrl and control files.

The free surface (i.e. the zero contour of the level set) inside the solid is a question of visualization. Your second image also indicates that your mesh is quite coarse, too coarse as it seems.

Another thing: you are starting with a free surface well below the weir, this I would not recommend.

I will try again with a smaller mesh size, thanks for the suggestion.
Best regards
