Hi, I have a 2D uniform mes
I have a 2D uniform mesh with 0.5<=x<=1, 0<=y<=0.5, created using blockMesh. I'm computing the following expression,
where x() and y() is defined in the following way,
tmp<volscalarfield> MSolution::x() const
For a small grid, 20x20 nodes large, this gives PMS=0.0 at the boundaryFields, (x=0.5, 0<=y<=0.5) and (y=0.5, 0.5<=x<=1). This is the correct behavior. The problem is when I increase the grid resolution to maybe 100x100. Then I get values that are not equal to 0 on the boundary. I think it's important to add that these values are of the magnitude 1e-18, quite small depending on the circumstances. I have checked the polyMesh directory and everything seems to be correct there. I really don't understand this. Any suggestions?
