Hi Everyone,
I am trying to calculate the dimensionless wall distance of a cell centroid. Are there any predefined macros available? I have tried using C_WALL_DISTANCE(c,t) but to no avail. Can you please help me? Best, Abdullah Case Western Reserve University |

F_STORAGE_R(f,t,SV_WALL_YPLUS) I think that you do not want to retrieve the value of y+ in a wall, but in a cell far from the wall. In that case, you can't directly access with a macro, you must use the equations of the law of the wall (check your ANSYS Fluent theory guide) and do the calculations, but it is not that simple. Check here the equations of the law of the wall: http://www.arc.vt.edu/ansys_help/flu..._th_stdwf.html Cheers |
