The mesh density in a finite element model is an important topic because of its relationship to accuracy and cost. In many instances, the minimum number of elements is set by topological considerations, for example, one element per member in a space frame or one element per panel in a stiffened shell structure. In the …
MSC Nastran contains a large library of structural elements. In many situations several elements are capable of modeling the same structural effects. The criteria for the selection of an element may include its capabilities (for example, whether it supports anisotropic material properties), its cost (in general, the more DOF an element has, the more expensive …
Question: How can I automate my FEA model check and validation? Answer: Most companies know that Finite Element Analysis (FEA) can be a very powerful and beneficial tool to support their product development process. In addition, most of these companies know that it can be a dangerous tool if not used properly. Any successful strategy that …
