There are a couple of free tools available, for example gmsh (take a search machine to find). However, I suppose you additionally need something with open sources to add your routines for automatic processing. This is not always the case with otherwise free tools. A good start to search for a suitable instrument is:

Hi all,

you will find Juan's link below my link via "Paul Heckbert's Collection of Mesh Generation Links". So anyway, there exists quite a number of tools and one has to check for oneself, which are the requirements the tools basically should provide (programming language, type of cells, 2D/3D, provided output formats etc.), unless one considers using a commercial tool. These are usually more general and provide a bandwidth of combinations, even macro writing for automation of processes.

There are many algorithms and software too available for it. However, in intersecting volumes refinement of mesh is always an issue. I am working on Fiber reinforced composites, in that I a required to do model the same. I am doing that in ANSYS. However, every time I mesh the volume, I receive warning of some elements and due to this you can't refine it.

Hi,

you can either use the tool ngrid or the meshing tool implemented in openfoam.

FreeYams might also be added to the list of surface mesh generators

Hi all,

I think SALOME can be a good choice: it's a free and open-source mesh generator:

Hi,

Have a look at geuz.org/gmsh/ , Gmsh is a 3D finite element mesh generator.

You could consider a different approach by using immersed boundary methods

you could get rid of panelizing, but you should have an approprite solver for the different subdomains + boundary conditions among subdoains and with the external

Discretizer would be very good for making structured meshes. if you are doing it for a fluid dynamic analysis using a code like openfoam then it will give you the ready to solve case files itself. give it a try...:)

And also read about CGNS i guess if you obtain the output in CGNS format then you can call it in C++ or Python

Hi,

Perhaps you could use one of the mesh generators by Jonathan Shewchuk (http://www.cs.berkeley.edu/~jrs/), triangle for 2D and stellar for 3D meshes. Dealing with geometries (like the intersecting cylinders) could also be handled by the GMSH (http://geuz.org/gmsh/) already cited here.

Hi,

Try with blue kenue it is a free source..........

Thank you all for your answers! Gmsh and Salome seem particularly promising for my needs.
