Hi all,  
What is the proper way of saving and loading a meshL in FreeFem?

To save a mesh, you use the command  
savemesh(Th,“Th.msh”);  
To load your mesh, you use the command  
readmesh(“Th.msh”);  
You will find many examples in the freefem documentation.

I am talking specifically about a meshL, so the .msh format doesn’t work. In the documentation, I couldn’t find an example for loading this type of mesh.  
Say ThL is defined as meshL, I can save it via:  
`savemesh(ThL,"ThL.mesh");`  
But I have trouble reading it back. This does not work:

```auto
meshL ThL; 
ThL = readmesh("ThL.mesh")

```

I think you should use `readmeshL`

> Th = readmeshL(“ThL.mesh”);
