Julia

FinEtools is a tool kit for constructing finite element solvers. Visit github to view and download the software, and to learn how to use the tool kit with examples and tutorials.

Please note that I no longer support Matlab software.

C and C++ software

The software below was written by Petr Krysl, unless noted otherwise in the source code (Meschach, c2man, and parts of Ckit and CVL).

NOTE: To install the software, download, uudecode, and untar by, for example,

      uudecode package.tar.gz.uu
      gunzip -qc package.tar.gz | tar xf -

That should create a directory of the name package with all the good stuff in it. The packages use the GNU configure scripts to customize settings for the particular computer you are installing on.
