PANSFEM2

is a FEM library for C++. This contains

Linear algebra models (Vector, Dense Matrix, Sparse Matrix)
Linear algebra solvers (CG, BiCGSTAB, BiCGSTAB2, Lanczos, ...)
FEM controller (Assembling system, Shape function, Integration method, ...)
FEM equations (Linear/Total Lagrange/Updated Lagrange solid, Heat transfer, Fluid, ...)
Optimization solver (OC method, MMA)

and you can easily create the simulation environment you need.

Build and Run

You can build and run a sample code as below

$ git clone https://github.com/PANFACTORY/PANSFEM2.git
$ cd PANSFEM2
$ g++ -O3 -fopenmp sample/solid/sample_updatedlagrange.cpp
$ a.exe

and you will get vtk format (*.vtk) result file.

This library has 3 advantages:

Template library
→ You only pass through the path and include this.
Various combination
→ You can select Equations, Shape functions and Integration methods.
Optimization
→ This program is originaly developed for Topology Optimization.
