MeshIt – a software for three dimensional volumetric meshing of complex faulted reservoirs MeshIt is a software for generating three dimensional high quality, boundary conforming Delaunay tetrahedral meshes for Finite Element (FE) or Finite Volume (FV) Thermo-Hydraulic-Mechanical-Chemical (THMC) dynamic simulations of complex faulted and fractured reservoir applications.

The main goal of MeshIt is to provide an open source, time efficient, robust and “easy to handle” software tool to bridge the gap between geological and dynamic forward models of flow and transport processes in reservoir domains comprising fault zones, wells (open hole section) and induced and/or natural fractures. MeshIt comes with an integrated graphical user interface (GUI) that facilitates the user during the different stages of the meshing workflows. The core of MeshIt has been developed with the support of the Integrated Development Environment (IDE) Visual Studio 2013 released by Microsoft.

Beside third party C libraries, the complete code has been written in the object oriented C++ programming language. In order to provide cross-platform support (Windows 7 & (Mac OS X and Unix operating systems under 32 and 64 bit) the open source project Qt has been integrated in the supported library environment.

The interactive 3D graphics Application Programming Interface (API) has been developed by relying on the OpenGL library. All graphical processing stages have been interfaced to the open-source, multiplatform visualization software Paraview, the latter being based on the Visualization ToolKit (VTK).
