# Meshing

**Overview**

- A
**List of meshing tools**that integrate with OpenFOAM.

**Geometry**

**Geometry creation**- Here you will get a detailed introduction into two alternatives for the creation of geometries as inputs for a CFD project in OpenFOAM.

**Meshing**

**blockMesh**- In the following tutorials you will find an introduction into meshing with the blockMesh utility: by Nagy,by Bahram Haddadi**snappyHexMesh**- This tutorial gives you an insight on how to create complex meshes within OpenFOAM and snappyHexMesh.**snappyHexMesh – Single region**- Mesh a flange geometry and simulate heat transfer in it using scalarTransportFoam.**snappyHexMesh – Multi region**- In this tutorial a geometry with more than one region is meshed using snappyHexMesh and simulated using chtMultiRegionFoam.**Meshing with cfMesh**- In this tutorial you will learn the basics of meshing with cfMesh.**How To Build a complete OpenFOAM Project - Exhaust manifold**- In this tutorial you will learn about meshing in a full simulation project.

**Moving mesh**

**Rotating Fan in Room**- In this tutorial you will learn how to run a rotating mesh simulation.**Sphere settling under the influence of gravity**- In this tutorial you will learn about the simulations with overset meshes.**Sphere settling under the influence of gravity with varying contact angle**- In this tutorial you will learn about the simulations with overset meshes and different contact angles.**2D flapping wing**- In this tutorial an additional application of the overset methodology is illustrated.**Inline oscillating cylinder**- In this tutorial we will examine the inline oscillatory motion of a cylinder in a uniform flow with morphing and overset mesh.

**Mesh dependence study**

**Transonic flow around a periodically pitching NACA0012 airfoil**- In this tutorial you will learn about the transonic flow around a periodically pitching NACA0012 airfoil including an extensive grid dependence study
