I am doing my project for school and have to create screw conveyor. I have already draw 3D model first on CATIA and then transfered it to Solidworks. I have connected all surfaces and is able to make animation of screw rotating inside of the pipe. However I need to simulate sand transportation inside of it. It goes from the grided whole on one side and comes out on the other side of the pipe moved by rotating screw. Can someone describe me how I can do that?
