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.

Selling point

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.

Samples
