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

  • Title:  PEEI

  • Version:


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