About PolyDE

PolyDE is not only just another library for finite element computation. It is rather a full FE package that can do fully automatic adaptive solutions to multi-nature problems, i.e., coupled-physics.

This version of PolyDe is a fork from the original https://sourceforge.net/projects/polyde-fem/ It is a sort of "lagging mirror" to the most up-to-date version there.

This fork is geared towards Linux, and a tighter integration with the latest Intel's oneAPI Fortran compiler and MKL library, and PETSc.

About this binary release: PolyDE v0.9.2309

This is release v0.9.2309 This binary release is compiled with Intel OneAPI Version 2023.1.0 on the Intel Core i5 CPU.

Prerequisites to build from the source

• A rather recent Linux distro, with libc close to version 2.36
• Intel's oneAPI collection including MKL
• CMake
• pgplot

Environment variable

Polyde only needs one environment variable: PolydePath

To set up, include the two lines in .bash_profile :

PolydePath=/home/your_user_name/Polyde/

export PolydePath

Compilation

Setup for compilation is as the standard procedure with CMake.

Running PolyDE

The two FEMsettings.txt should be properly set up.
