Fem Finite Element Method. Number of degrees of freedom dof. Dividing the domain of the problem into a collection of subdomains discretization with each subdomain represented by a set of element equations to the original problem the creation of finite element meshes the definition of basis function on reference elements also called shape functions the mapping of reference elements onto the.
But what exactly is it. Fem cuts a structure into several elements pieces of the structure then reconnects elements at nodes as if nodes were pins or drops of glue that hold elements together this process results in a set of simultaneous algebraic equations. Once the integral or weak form has been set up the next step is the discretization of the weak form.
Number of degrees of freedom dof.
The finite element method fem was independently developed by engineers beginning in the mid 1950s. Once the integral or weak form has been set up the next step is the discretization of the weak form. The fem generally addresses issues in heat transfer structural analysis fluid flow electromagnetic potential and mass transport. The method started with promise in the modeling of several mechanical applications in the aerospace and civil engineering industries.
