Is it possible to directly create nodes and elements in FreeFEM? I am working on a structural optimization application and I am doing the meshing myself. I couldn’t find anything in the documentation.

If you are doing the meshing yourself, using some custom mesh generator I guess, then couldn’t you create nodes and elements yourself as well? What would be the exact use case, please?

Yes, I’m looking for the syntax to create a node, and the syntax to create an element.

to day they is no way to create mesh or element, the easy way is to can create a file en read the file.

I see them used in the documentation, but I haven’t found a specification for those files yet.

Ah, found it here:

[https://doc.freefem.org/documentation/mesh-generation.html](https://doc.freefem.org/documentation/mesh-generation.html)

In the section titled: “Read/Write Statements for meshes”.

Thank you for your help
