WebMy solution is crashing early in the solution with "bounding epsilon" and I can't figure out why. I have a feeling that the problem is with my pressure BCs. Using tutorials as reference, I set only the fixed value as 100kPa for the outlet in the p_rgh field with other patches and walls as fixedFluxPressure. http://jimhawley.ca/downloads/Plotting_OpenFoam_residuals_and_forces_in_real_time.pdf

[cx, cy, cz, rot_z, length, width, height] to an array of points that represent the 8 corners of the box. You can use a function like this, that takes an array containing [x,y,z,h,w,l,r], and returns an [8, 3] matrix that represents the [x, y, z] for each 8 ...
