Tessellator 4 GiD mesher

This fork is to adapt the Tessellator mesher for GiD.

Features

Tessellator is a mesher focused on generate meshes and data structures which are suitable for FDTD algorithms. It includes the following capabilities:

• Generate staircased meshes from lines, surfaces, and volumes.
• Support for rectilinear (graded) grids.
• Import/Export in STL or VTK formats.
• Conflict resolution between different layers using a predefined hierarchy.
• Generate conformal meshes with fixed distance intersection with grid planes.

Compilation

When using presets, make sure to define the environment variable VCPKG_ROOT to your vcpkg installation. This can be done using a CMakeUserPreset.json file, for example:

{
  "version": 4,

  "include": ["CMakePresets.json"],
  "configurePresets": [
    {
      "name": "gnu-local",
      "displayName": "GNU local",
      "environment": {
        "VCPKG_ROOT": "~/workspace/vcpkg/"
      },
      "cacheVariables": {
        "TESSELLATOR_ENABLE_CGAL": true
      },
      "inherits": "gnu"
    }
  ]
}

Compiling + Building with already installed vtk / boost / gtest

echo "we are in tessellator base dir"
mkdir build
cd build
cmake -DBoost_INCLUDE_DIR=/...path.to../boost_1_75_0/   -DCMAKE_INSTALL_PREFIX=$HOME ..
# eventually add -DVTK_DIR=/..../VTK/windows/vtk-8.0
