Hi !!


I am giving my checkMesh results with some images of the mesh. Overall domain bounding box (-2.500042546 -2.500042549 -2.5) (2.500042479 2.500042481 2.5)
Mesh has 3 geometric (non-empty/wedge) directions (1 1 1)
Mesh has 3 solution (non-empty) directions (1 1 1)
Boundary openness (-1.694856469e-17 3.009640066e-17 -7.821753458e-16) OK.
Max cell openness = 3.744188186e-16 OK.
Max aspect ratio = 5.877757993 OK.
Minimum face area = 5.278152888e-08. Maximum face area = 0.0101113708. Face area magnitudes OK.
Min volume = 5.7498987e-10. Max volume = 0.001010488176. Total volume = 124.2733063. Cell volumes OK.
Mesh non-orthogonality Max: 61.89625939 average: 4.76190501
Non-orthogonality check OK.
Face pyramids OK.
Max skewness = 3.872508738 OK.
Coupled point location match (average 0) OK.
Mesh OK.


With this mesh when I am running the simulation (dbns-> Roe Flux ->Venkatakrishnan limiter) with blade rpm of 1250, the maximum velocity is becoming too high. Can skewness be the cause of the unphysical simulation? The radius of the blade is 1.48m, NACA 0012 and pitch angle is 8deg.


Is it possible to find the most affected cells in paraview?
