Problem with Mesh Volume
I am struggling with a Problem for several weeks already and starting to get really desperate. I have posted it in the main forum already, but I figured posting a new thread here as I have narrowed the problem down to blockMesh, I guess so at least.
The Problem is I want to simulate a thin layer with a bump, I have modelled the bump with a blockMeshDict.
What is wrong here is that the volume is not recognized correctly. You can see in checkMesh the total volume of 1256.62. But this cannot be correct, since a flat disc with height one and radius 20 would have exactly that volume (Pi*r^2)
But the graphical output in paraview is correct. Whats wrong here? :(
Now when I do checkMesh, this is the output
I don't see you problem. Your formula is right and I get:
So for me everything seems to be fine.
well the problem is the volume must be larger than this.
See the attached picture, its a bump and not a disc anymore. The Problem is similiar to taking a cube and a cube with a large dent in it but with the same length of the edges. The volume should be different
To illustrate my problem I have made 2 more screenshots. In the first picture you look from on top on the geometry.
In the second picture is the same geometry with a different angle of observation. checkMesh reports no errors and a total volume of:
On the second picture you see the real geometry and clearly the volume must be larger...
I really have no idea what is going wrong here :(
