# netgen(1)

Automatic 3d tetrahedral mesh generator

## NAME

netgen — Automatic 3d tetrahedral mesh generator

## SYNOPSIS

**netgen** \[OPTIONS...\]  \[file.geo\]

## DESCRIPTION

This manual page documents briefly the  **netgen** and **bar**       commands.

This manual page was written for the **Debian** distribution  because the original program does not have a manual page.

**netgen** is an automatic mesh  generation tool for two and three dimensions.  Netgen generates  triangular or quadrilateral meshes in 2D, and tetrahedral meshes in  3D.

The input for 2D is described by spline curves, and the  input for 3D problems is either defined by constructive solid  geometries, or by the standard STL file format.  Netgen contains  modules for mesh optimization and hierarchical mesh refinement.  Curved elements are supported of arbitrary order.
