enGrid

enGrid is a mesh generation software with CFD applications in mind. It supports automatic prismatic boundary layer grids for Navier-Stokes simulations and has a Qt based GUI.

A Doxygen created source code documentation can be found here:

http://todtnau.engits.de/engrid-doc/master/html

The documentation is updated automatically and should contain the correct documentation latest one day after a commit to the master branch.

Building enGrid

Due significant changes to the enGrid codebase, only the master branch version of enGrid is actively supported. The code now makes use of the CMake build system, which should simplify compilation.

The main dependencies for enGrid are:

  • Qt 4
  • VTK 6.*
  • CMake
  • CGAL

VTK needs to be compiled with Qt support, as enGrid depends on QVtkWidget. The plan is to move to qt5 in the near future, which would also allow to upgrade to the latest version of VTK.

enGrid was successfully compiled on Ubuntu 16.04 (Xenial Xerus) with the following dependency versions:

  • Qt 4.8.7
  • CMake 3.5.1
  • VTK 6.2
  • CGAL 4.7-4

As Ubuntu 16.04 only has Qt 5 support for VTK, VTK had to be compiled locally. The VTK build was configured using the following command:

cmake -DCMAKE_BUILD_TYPE=Release -DVTK_Group_Qt=ON -DCMAKE_INSTALL_PREFIX=/the/path/of/your/choice

enGrid can then be configured and compiled in a separate build directory using:

ccmake ..\src

pressing [c] to configure, pressing [c] a second time to accept the changes, and pressing [g] to generate the Makefiles and exit. The code can then be compiled and installed using make:

make -j8 install

You can’t perform that action at this time.
