Finite element model data post-processing is a paradigm for transforming the often highly detailed and complex outputs of [[Finite Element Method|Finite element models]] (FEM) into a format that is easily understood by the user. The outputs from post-processing may be used in engineering judgements or analysis, as part of validity/functionality checks on the FEM model, or for the purpose or reporting results. |

[[Finite Element Method|Finite element models]] (FEM) are nowadays used to calculate complex structures and mechanical systems. Since the grown calculation capacity of computers makes it possible to make more and more detailed [[Finite Element Method|finite element models]], the file output of these programs can be enormous. It can be so large that you need to ''post process'' this data. Postprocessing may be defined as the “art of results representation”. |

Finite element model data post-processing is a paradigm for transforming the often highly detailed and complex outputs of Finite element models (FEM) into a format that is easily understood by the user. The outputs from post-processing may be used in engineering judgements or analysis, as part of validity/functionality checks on the FEM model, or for the purpose or reporting results.
Post processing of finite element data generally requires additional software or programming to specify how the data is to be transformed or presented [1]. This software may include checks on the codes and standards to which the model must comply e.g. the check of panel stiffened structures. Using this software can be considered part of the knowledge-based engineering principle.
