Document Summary

Setting plot scale to true, can get realistic idea of how much the plunger traveled under the load. Presence of bolts requires a lot of computing power in assembly. Can eliminate bolts along with its washers and nuts and use simulation bolt connectors. Can include mass (checkbox in the same feature manager. Need to do this for each bolt. Simulates the behavior of components that are spot welded together. Results obtained through the use of spot weld connectors should be used for the determination of deflection and global stresses, not stress concentrations at the weld sight itself. Selection field for the two touching faces. Third selection field is for the position of the spot weld. Can use assembly level reference points or by selecting vertices. Meshing techniques we went over include shell elements, beam elements, and localized mesh refinement. Adaptive methods, on the other hand, are not manually set by us. We allow the simulation to automatically make the adjustments.
