Computation and Verification of Data
Barna A. Szabo, Ivo M. Babuska · 2011
At the end of the solution process the finite element solution is stored in the form of data sets that contain the coefficients of the shape functions, the mapping functions and indices that identify the polynomial space associated with each element. Some of the data of interest, such as temperature, displacement, flux, strain, stress, can be computed from the finite element solution either by direct or indirect methods while others, such as stress intensity factors, can be computed by indirect methods only. The techniques used for the computation and verification of engineering data are described.
