Download and Installation

Download: wenbinyugroup/prevabs

Prerequisites

Download and install VABS (with valid license) if you intend to run VABS analyses. In the instructions below, VABS_DIR refers to the path to the VABS executable. VABS manual can be found and downloaded here .

PreVABS itself does not require Gmsh to be installed separately — its meshing capabilities are provided by the Gmsh library which is bundled with the PreVABS distribution. Installing the standalone Gmsh GUI from https://gmsh.info/ is still recommended if you want to inspect generated .geo_unrolled / .msh files outside of the PreVABS workflow. In the instructions below, GMSH_DIR refers to the path to the Gmsh executable (only needed if you install Gmsh separately).

Install binary

Obtain a PreVABS release archive (or build from source — see the project README) and unpack it to any location. In the instructions below, PREVABS_DIR refers to the path to the PreVABS executable;

Add those paths to executables to the system environment variable PATH;

On Windows:

Open Environment Variables editor. Edit user variables for your account or edit system variables if you have the administrator access. Add VABS_DIR, GMSH_DIR, and PREVABS_DIR to the variable PATH.

On Linux:

In the shell, type:

export PATH=$VABS_DIR:$GMSH_DIR:$PREVABS_DIR:$PATH

To make this effective each time starting the bash, you can add this command to the bash startup file, which may be ~/.bashrc, ~/.bash_profile, ~/.profile, or ~/bash_login;
