Yes, there are several CFD software applications that can be used to generate an O-grid mesh for airfoil flow simulations. Here are a few popular ones apart from Pointwise:
ANSYS Fluent: ANSYS Fluent is a widely used CFD software that offers meshing capabilities including the generation of structured O-grid meshes. It provides a variety of tools and options to create O-grids around complex geometries like airfoils.
OpenFOAM: OpenFOAM is an open-source CFD software package that includes meshing utilities capable of generating O-grid meshes. Users can utilize the snappyHexMesh tool within OpenFOAM to create structured grids around airfoil geometries.
NUMECA: NUMECA is a commercial CFD software suite that provides advanced meshing capabilities. With tools like AutoGrid5, users can generate O-grid meshes suitable for airfoil simulations. NUMECA also offers the possibility of performing immersed boundary simulations.
COMSOL Multiphysics: COMSOL Multiphysics is a multi-physics simulation software that includes a dedicated CFD module. It offers meshing functionalities for generating O-grids, including around complex geometries like airfoils. COMSOL also provides features for immersed boundary simulations.
These are just a few examples of CFD software applications that can generate O-grid meshes for airfoil flow simulations. It's worth noting that different software packages may have varying levels of ease of use, capabilities, and specific features.
So it's recommended to explore their respective documentation and resources to determine the most suitable one for your specific needs.
Please find attached some pictures of the O-grid. The boundary conditions are as follows:
The boundary conditions are periodic along the xi and zeta directions.
On the outer eta boundary, an inlet velocity condition ($u_x = U$) is specified for $x0$, a Neumann boundary condition with a mass flux correction is applied to represent the downstream region.
We initially used pointwise to make the mesh but the license expired. We are trying to explore other CFD software that could be used to generate an O-grid mesh for our immersed boundary method.
