Finite-element analysis, or the finite-element method (FEM) as we will call it, hides plenty of traps for uninitiated users. Errors that come from idealization and meshing a part can be bad enough to ...

Doing so brings simplifying assumptions that cause modeling errors to the math model. A correctly formulated mathematical model captures the characteristics of an object needed to make design ...

Partial differential equations (PDEs) are often utilized to express space- and time-dependent problems in physics, however, when applied in geometry and for the solving of other related problems, ...
