Witryna3 kwi 2011 · 3 04 2011. >. Implicit and Explicit are two types of approached that can be used to solve the finite element problem. The implicit approach is useful in problems in which time dependency of the solution is not an important factor [e.g. static structural, harmonic, modal analysis etc.] whereas Explicit Dynamics approach is most helpful … WitrynaBenefits of FEM and FEA. Improved accuracy and enhanced design: FEM and FEA allow for enhanced accuracy of structural analysis because they give insight into how the various elements of a design are interacting in minute detail. They also allow engineers to investigate both the interior and exterior of a design.
