I am trying to simulate the mhd flow in OpenFoam using mhdFoam.
at B=0 one should get parabolic profile but at nu=0.0000001 I am not getting the parabolic profile

My properties are
rho rho [ 1 -3 0 0 0 0 0 ] 9926;

nu nu [ 0 2 -1 0 0 0 0 ] 0.0000001;

mu mu [ 1 1 -2 0 0 -2 0 ] 1*e-6;

sigma sigma [ -1 -3 3 0 0 2 0 ] 8000;

but at the same time I am getting the required profile when I put nu=0.000001
at U=0.0001.
what is the reason behind this??
please help

thanku
