Dear Foamers,

I have seen a fantastic feature of Fluent. The mesh motion is possible through an automatice re-meshing. Let's say, for example, that I wanna open a door. I create a single mesh and then launch the simulation and the software first strech the cells and then - when the skewness reaches a certain values - the solver itself do a remeshing.

Is there something similar in OF? Or we have only a tool that stretch the mesh?

Thanks a lot,

Samuele

Yup. You can find it here:

That's nice.

How does this work? Is it downloadable?

Can you help?

I can be a good tester

..

Thanks,

Samuele

The non-parallel bits are already part of OpenFOAM-extend.

With parallel functionality, you'll have to check it out from the repository. Installation instructions are here:

I believe Kyle Mooney has already prepared documents / presentations on usage of the class at the recent OpenFOAM workshop, so if you go through the archives, you should find them there.

Can I share my case in order to understand if someone can help?

How can I do this?
