ParallelFEM-Fortran

Parallel programming for Finite Element Analysis using FORTRAN and PETSc

This code includes several parallel implementations for the Lapalace equation and linear elasticity in 2D and 3D. This code has been tested on HPC machines at Swansea University.

Please report if you find any issues/bugs.

Compilation steps

  • Enter bin directory using cd bin
  • Modify the makefile as per the location of the PETSc library files in your system
  • Execute make <exename>. This will also compile all the dependencies.
  • For example, to build tetrapoissonparallelimpl1 use the command make tetrapoissonparallelimpl1

Step-by-step guide

Refer to the PDF for the details on data structures and some discussion on the parallel programming for FEA.

Some examples

Poisson equation in 3D with 200x200x200x6 (= 48 Million) tetrahedral elements

Linear elasticity in 3D with 50x300x50x6 (= 4.5 Million) tetrahedral elements

pfemfort's Issues

About dealing with domain with different type of elements

Dear Dr chennachoas,

I very am happy to see an open source fortran code for entire implemetation of parallelization of FEM in 3D, thanks for this great work.

I may have one question that, if considering the domain with different type of elements in 3D, such as C3D4 (tet), C3D8(hex), ETC.... is it also possible to deal with this situation in parallelization in building the element jacobian and assemblying them?

I am looking forward to your suggestions.

Best wishes,
Tongrui
