Fea symmetry
WebApr 19, 2011 · Symmetry- stupid question. I have a structure and I only model half of the structure due to symmetry. The structure is exposed to an impact of an sphere in the middle of the structure, this is modeled by a prescribed displacement of the sphere. . Due to this I only model half the structure and half the rigid sphere. WebMar 28, 2024 · Symmetry. One of the easiest and most effective ways to reduce the computational time is to simulate symmetric sections of the design. Most structures and their loads are symmetric, usually about a plane, line or axis. A big advantage of identifying symmetric geometry is the simplification of the associated FEA problem, thus reducing …

WebIf a structure is symmetric, then the size of your finite element model can be reduced, which, in turn, reduces the time and cost of your analysis. For each plane of symmetry that you … Websymmetry can be used. These include mirror symmetry constraints and cyclic symmetry constraints. Mirror symmetry constraints cut a model through a plane about which it is symmetrical. To do FEA analysis, one need first build …

In thermal FEA you can simulate only cyclic symmetry and not mirror symmetry. In cyclic symmetry you have to model a certain angular segment of the whole model and the whole model should be generated if we revolve one of the symmetry surfaces by a certain angle.
