Appendix X.B
Coordinate system transformations

The modification of coordinate system into which the components of vectorial or tensorial results are expressed is a common operation performed when post-processing finite element results. To perform the transformation some vectorial and tensorial calculation is necessary. One gives in this Appendix, a summary of theoretical background necessary to understand the operations performed with FeResPost.
