"Web1 Answer. For visualizing the bounding boxes, you'll have to convert the boxes from. [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 ... " - Openfoam bounding epsilon

Download the CAD File: WebThe second one is to use the PIMPLE algorithm in the correct way. The PIMPLE algorithm combines the PISO with the SIMPLE. That means, the problem is transient but we use the SIMPLE (steady-state) treatment to find the steady-state solution for each time step. This allows us to increase the Courant number larger than one.

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.
