However, the solver doesn’t know that, so it will assume you need all nodes solved. If all loads and fixtures are the same, then the displacements and reactions on the 25,000 nodes on one side will be identical to the other. Consider this: Imagine a model of symmetrical shape, like a rectangle, that has 50,000 nodes. I know people tend to think of cutting models in half as extra work, but it really isn’t. This is applicable whenever parts have symmetry, which they usually do, sometimes even two points or axis symmetry. ![]() The Chainsaw is the tool you use to cut models in half and then only solve that half. ![]() (*Most simulation engineers don’t work 24/7.) Seasoned simulation engineers (people who run simulations almost 24/7) are constantly thinking about how to go about setting up, troubleshooting and post-processing models. Knowing what these methods are, what they do and why and when you would use them will allow you to think like a simulation engineer. I like to talk about six tools of the trade when I talk about setting up simulation models that I have affectionately named: the Chainsaw, Virtual Reality, the Transmogrifier, the Reverse-3D Glasses, the Doctor and the Jedi Mind Trick.
