Hi,

I am using chtmultiregionfoam with an incompressible fluid in an enclosed volume. I have noticed that I am getting weird results at just one point in the volume while everything else is solving as expected. It appears that the density at the pressure point constraint is lower than the rest of the volume. I can tell that it is at the pressure point constraint because I changed the pressure point from prefCell to prefPoint and began solving again and the density changed at the new location (see screenshots attached).

Has anyone else experienced this?

Kind regards,

Declan
