EQP Equivalent Polynomials Library - A 2D/3D library for integration of polynomials times step function

Currently, EQP Library includes functions for the evaluation of Equivalent Polynomials for the following linear 2D and 3D finite elements: linear triangle; linear quadrilateral; linear tetrahedron; linear hexahedron.

The EQP Library archive download contains: a pdf application note illustrating the Library and its usage; the FORTRAN90 source code of the Library; a FORTRAN90 usage example file the BibTeX file of the References to be cited to support the deelopment work of this Library
