RTFEM

RTFEM stands for Real-Time Finite Element Method.
The library computes the entire process of Finite Element Method for solid mechanics in real time, namely:

1. Pre-Processing:
   • 3D Finite Element Meshing of given geometry.
2. FEM Solver:
   • CPU and GPU Linear elastic, linear deformation, dynamic.

Supported Platforms

Library is written in c++11.

• Linux 32/64bit
• Windows 32/64bit

Build

RTFEM can be built on any platform supporting cmake.
To build the library, run the following command in root directory:

cmake .

Requirements

The following software is required to be installed:

• Cmake 3.3
• CUDA 8
  • Set environment variable CUDA_BIN_PATH to root directory (e.g. /opt/cuda/)

External Dependencies

External Dependencies can be found in ./external and tests/external directories.
These are installed automatically when using cmake installation.

• TetGen (external/tetgen1.5.0)
  • 3D Tetrahedron meshing algorithm
• Eigen (external/eigen)
  • Matrix operations and System of Linear Equation Solver
• googletest (tests/external/googletest)
  • Unit testing

Unittests

Building Unittests can be disabled/enabled in CMakeLists.txt.
Unittests are written using googletest
