Variable mass scaling is used to efficiently model the phenomena in their natural time scale using a Lagrangian formulation.What is the number of degrees of freedom of a finite element?In general, the number of degrees of freedom associated with a finite element is equal to the product of the number of nodes and the number of values of the field variable (and possibly its derivatives) that must be computed at each node.See all results for this question

### What is finite element method?

The finite element method (FEM) is the dominant discretization technique in structural mechanics. The basic concept in the physical interpretation of the FEM is the subdivision of the mathematical model into disjoint (non -overlapping) components of simple geometry called finite elements or elements for short.See all results for this questionWhat are interpolation functions?The interpolation functions are predetermined, known functions of the independent variables; and these functions describe the variation of the field variable within the finite element.
