Hi all
I have a rotating cylinder in my problem. I used rotationBC to get the good BC for U, but now I refine the mesh and I get weird BC. The diameter is 0.2, and the angle speed is 100 rad/s (20 m/s on perimeter). The BC begin with : wheel { type fixedValue; value nonuniform List<vector> 1043 ( (-8.479432e-44 0 -0) (20 8.750005 -0) (20 9.050035 -0) (20 40.45565 -0) (20 237.475 -0) (20 239.475 -0) (20 9.85393 -0) (15 35.76775 -0) (20 9.150045 -0) (20 9.75086 -0) (20 9.350065 -0) (20 35.7176 -0) .... (20 360.4865 -0) (20 358.486 -0) (20 365.487 -0) (20 364.487 -0) (20 332.484 -0) (20 335.484 -0) (20 277.4785 -0) (20 272.478 -0) (20 316.482 -0) (20 394.49 -0) ... rotationBCDict contains : wheel { omega 100; axis (0 0 1); centre (0 0.2 0); } What can be wrong ? |
