Cartesian meshes in this software is generated from the model geometry. The software runs Boolean operations to determine the internal and external fluid volumes which are then captured by the grid. In that sense, the mesh is dependent on model geometry, but these aren’t body fitted meshes. The software uses algorithms to resolve non-orthogonal geometry. Thank you.
Is it possible to know for a particular refinement level in global mesh settings, what element size we will get. Like for the given domain, refinement level 1 corresponds to 'x' mm element, level 2 corresponds to 'y' mm. Like that....
The cell sizes from the refinement levels are relative to the Global Initial Mesh Size. For a certain initial mesh size, each level of refinement will yield 8 additional cells in the space occupied by each initial cell. So level 1 will yield 8 cells, level 2 will yield 64 cells and so on. This is described at 8:00 in the video. Thank you.
@@goengineer Thanks for the reply GoEngineer. That I understood. But if you take any CFD problem, they will talk y+ and y* values which corresponds to a specific first cell height. So will it be possible to give the same kind of input we calculated or not. I have seen equidistant mesh refinement option in FloEFD which lets us to give 1st, 2nd and 3rd layers height. Is it related to what I mean? If so please confirm. Thanks again... 🙂
Mr. Arun: I developed a heatsink similar with 4 bars of copper and blades, but using two funs... using the local mesh, with 4 channels and 4 level mesh and advanced refinement and the cpu time is a lot, around 40minutes in finish just the mesh. how many late in charge your mesh in your heatsink? it has 52 plaques, and the minimus gaps is 1.7mm. Every plaque is 0.3mm of width and the computation domain has a symetric axe. and my computer is a i7 intel of 3,4GHz, memory card 2Gb, 24Gb 1300 Ghz and a solid state disk your video is really interisting, thanks a lot. Mechanical Engineering.
