Dear colleagues,

I am happy to inform you that cfMesh-v1.0.1 and cfSuite-v1.0.1 are now available for download. We have also improved and updated the installer of our Windows ports with OpenFOAM-2.3.0 and foam-extend-3.1. For more information, please check: http://www.c-fields.com/blog/release-101

Best Regards,

Franjo

I just thought about a possible enhancement. How about adding a factor that controls the size of the octree? Sometimes one might want to change the cell size on a finer scale than one octree level, e.g. use 1.5 times the amount of cells of one octree level.

Would this make sense?

Hi
Can I use cfmesh for MRF problem in OpenFOAM?
Thanks

@chriss85: If I understood you correctly, the idea is to have a more uniform cell size in the mesh. Currently, by using the cartesianMesh the edge length vary by a factor of 2, and the volume of cells by a factor 8. We will consider this for future development.
My impression is that this problem is not so apparent with the tetrahedral template, and the template consisting of arbitrary polyhedra which we plan to release with the new version.

@aminem: Currently, cfMesh generates a mesh without the cell zones needed to set up MRF. You can generate the cell zones by using the setSet and setsToZones utilities available in OpenFOAM. I am interested in getting more details about your requirements in order to provide a viable solution to these kinds of problems in the future releases of cfMesh.

Creative Fields, Ltd. is proud to announce the v1.1 release of cfMesh.
The major focus of the release was on implementing important new features, from which the most important ones are:

• boundary layer optimisation,
• anisotropic meshing,
• polyhedral meshing workflow,
• possibility to stop and restart the meshing process,

all in order to further improve mesh quality and allow more control to the user.
With this release, users will benefit from:
1. Boundary layer optimisation procedure – improves quality and stability when many layers are required. The feature allows you to successfully generate meshes with many layers for complex geometries.


2. Anisotropic meshing – regions consisting of anisotropic cells are defined via box and plane primitives.


3. Workflow controller – allows the user to interrupt the meshing process and write out intermediate meshes. It is possible to restart from the latest saved step. The important purpose of the feature is to allow user notice problems early in the meshing process

4. Meshing workflow generating arbitrary polyhedral cells.

The user guide and the tutorials are available in the download packages.

The detailed release notes are available here.
The source code, the installation packages for 64-bit Linux and the installation package for 64-bit Windows are available at: SourceForge.net. The access to the online git repository is available here: git clone git://git.code.sf.net/p/cfmesh/code cfMesh.
If you are interested in hearing more about cfMesh, contribute to the project,or give us your feedback, please contact us.
cfMesh is a cross-platform library for automatic mesh generation that is built on top of OpenFOAM. It is licensed under GPL, and compatible with all recent versions of OpenFOAM and foam-extend.
