FEDOF

Data type for finite element degree of freedoms. FEDOF_ defines the abstract node in finite element method. The basic steps of using this data type is given below.

Basic usage

Constructor methods

There are several ways to initiate an instance of FEDOF.

CALL obj%Initiate(order,  mesh, baseContinuity, baseInterpolation, ipType, basisType, alpha, beta, lambda)

• Here order represents the order of each element.
• It can be a scalar, vector, or a two dimensional matrix.
• The method with scalar order is given here.
• When it is a vector then it represents the order of each cell element. This method is given here
• Then order is a matrix then the first row represents the global number of cell element, and the second row represents the order of cell element. This method is given here

You can also initiate an instance of FEDOF using ParameterList. The process is given below.

• First, set parameters in ParameterList object by using [SetFEDOFParam].
• Then, initiate an instance of FEDOF using ParameterList object by using Initiate

CALL obj%Initiate(param, mesh)
