AdaptTools

This directory contains a set of tools for mesh adaptation intwo and three dimensions. They can be used and combined in a Linux/Unix/Posix-compliant shell script wrapper or called as functions from C/C++/F programs.

Mesh adaptation

Mesh adaptation strategy has proved to be very efficient in numerical solutions of PDEs. The ability to adapt the elements geometric properties (size, shape and orientation) according to specific quantities related to the data greatly improves the accuracy of the solution and the convergence rate of numerical schemes.

The approach pionneered in our group (F. Hecht et al.) relies on the construction of nearly uniform simplicial meshes in a metric space. The underlying metric is related to the (approximate) Hessian of the solution of the problem.

Installation

1. Install the ISCD Commons Library on your system. Please refer to the instructions provided on the ICS Commons Library page in order to install this library.

2. download the zip archive of AdaptTools or clone this repository:

   git clone https://github.com/ISCDtoolbox/AdaptTools.git

   navigate to the downloaded directory:

   cd AdaptTools

   create a build directory and compile with cmake

   mkdir build
   cd build
   cmake ..
   make
   make install
   

Remark on mshmet software

• The master branch provides a library mode but, for now, 3D meshes aren't handled;
• the olderVersionThatWorks branch provides metric computation for both 2D, 3D volume and 3D surface meshes but doesn't provides the library mode.

Authors & contributors

• these tools have been developed and contributed over the years by several contributors. Main developers are Charles Dapogny (Université J. Fourier), Cécile Dobrzynski (Université de Bordeaux, INRIA) and Pascal Frey (Université Pierre et Marie Curie).
• Contributors to this project are warmly welcomed.
