Hello FreeFem team, thx to make such a perfect tool for us; I recently tried to add the [Mshdist](https://github.com/ISCDtoolbox/Mshdist) into FreeFem; However, the Mshdist uses the xxx.mesh or .sol files as its input, as my understanding, FreeFem needs to transfer whatever mesh objectives treated in FreeFem [such as the class defined in msh3.hpp] into the objectives used in Mshdist; I found out that this conversion is similar to add the mmg3d lib under 3rdparty into FreeFem; Unfortunately, there is little information I can find out about the msh3 class and I am also unable to catch up the information from the FreeFem source code; So would it be possible to add this lab into FreeFem or if I can hear any guidance from you?

Thank you very much.

Do you know you can use the `distance` plugin as well? See [distance.edp](https://github.com/FreeFem/FreeFem-sources/blob/master/examples/plugin/distance.edp) and other examples.  
I’m working on a fork of Mshdist which I plan on integrating inside FreeFEM, but in the meantime, I hope the `distance` plugin will do the trick for you.

Yes prj, Thx for the reply; I know the distance plugin of freefem, but it does not work well in my case;

Also, `.mesh` and `.sol` as generated by FreeFEM are usable by Mshdist. So you should be able to use it through and `exec("./mshdist ...");` call in your `.edp`.
