have a membrane that measures approx 80mm*40mm*0.25 mm. The pores/tubes inside it are inclined at 41.3 degrees to the X axis. Each pore is 1.8 nanometre. The condition is: There must 7 pores in 0.8 mm or 7*7 pores in 0.8mm*0.8mm
Im working on making the geometry before meshing, but since the tubes are in nanometre the software isn't allowing me to do anything. What if I have to make the tube dimensions to 1.8 mm instead of 1.8 nanometre. How do I change the other parameters/scale it in a way that the condition is satisfied. I am using Catia v5 for geometry. Also I want to work at a minimum of mm scale so as to have a proper mesh later
