problem due to reconstructPar?
 
SHM quality check:

Iteration 8
Moving mesh using diplacement scaling : min:0 max:1
Checking faces in error :
non-orthogonality > 65 degrees : 0
faces with face pyramid volume < 1e-20 : 0
faces with concavity > 80 degrees : 0
faces with area < 1e-13 m^2 : 0
faces with skewness > 4 (internal) or 20 (boundary) : 0
faces with interpolation weights (0..1) < 0.06 : 0
faces with volume ratio of neighbour cells < 0.025 : 0
faces with face twist < 0.05 : 0
faces with triangle twist < -0.99 : 0
faces on cells with determinant < 0.001 : 0
