PEEI: a computer program for the numerical solution of systems of partial differential equations.

  • Title:  PEEI

  • Version:   2.2.0.0

  • Author:   GIACOMO LORENZONI

  • Description:   PEEI calculates a numerical solution of almost all the systems of partial differential equations who have number of equations equal or greater of the number of unknown functions.

  • Date of release:   26 October 2008

  • Improvements respect to the previous version 2.1.0.0:   Any order of derivation also in the input file labeled "conditions". Better reading of input files, and possible insertion in them of comments that do not contain numbers. Removed a small GUI defect.

  • Later version:  3.0.0.0 . This later version has better management of execution, memory and user interaction.

  • License:  Freeware, PEEI is a completely free program, for unlimited personal and business use, designed realized and distributed by Giacomo Lorenzoni.
