Autodesk Inventor Mesh Plus A PaneI have a simple 5-part assembly - four aluminum extrusions that create a rectangular frame, plus a pane of glass that the frame supports.The frame is pinned on the top and bottom, and I want to measure deflection under a 30psf wind load from one side. I keep getting mesh failures though, and I dont understand why. The current problem is a surface meshing - a little fillet on one of my extrusions cant be meshed. I toggled ignore small geometry with disastrous results and adjusted the mesh element size too and nothing seems to help. Also, is it normal that the grid construction simulation each take up to an hour to complete Im running on a fairly well equipped desktop. Try using the Derive to a single IPT file and try the FEA there if you dont requre Dynamic Simulation. The IAM is only a wrapper that controls the assembly and location of the IPT files. Attached here. My aluminum frame extrusions have some shape to them - a few t-slots are extruded into their walls, which are basically U-channels. Disabling those features greatly reduces the usefulness of the stress analysis; what I want to see is whether my extrusion is strong enough to resist deflection under wind loading, so I really want to test the actual profile Im using. What do you mean by using the Derive to a single IPT I need to know how the aluminum frame affects deflection in the glass, and unless Im mistaken the only way to do that is through an assembly. I guess I could make my frame a single IPT instead of four IPTs. Its possible Im missing some larger point about meshing, I just cant see what it would be. I tried reducing the average element size to.060 and got a face failure. The parts will mesh without issue in versions newer than R2010. I beleive whats causing the mesher trouble are the long, thin faces. If we use the split command to decrease the length of the faces, the parts will mesh (attached).
