We are investigating using flow simulation for some of my company's products and I have a question about the flow simulation meshing. First first impression is why in flow simulation is the available mesh squares??? I have never seen this in our time of using similar products in the past. Is there a way to bring in a tetrahedral mesh from simulation into flow simulation? Honesty I have not played with it that much but I can't seem to find a way to bring in any meshing tools into flow simulation besides making the square meshing smaller... If someone could let me know if this is possible and point me in the right direction it would be appreciated, thank you in advance.
