Bug with the Lagrangian module and restart on a different Mesh - CS 7.2-alpha revision fb85c8cdc

[YohannEude]

Hello,

I have a problem when I try to do a restart with the Lagrangian module (and Vof) with a different mesh. I am using CS 7.2-alpha revision fb85c8c.
With the VoF module only, the restart on a different mesh works properly but when I add the Lagrangian module CS crashes.
During my tests, I tried to do a restart (iso mesh) by specifying a "different mesh" in the GUI while I keep the same mesh in MESH and I get the same bug:

/home/yohann-ws2/Development/CS_MASTER/code_saturne/src/lagr/cs_lagr_restart.c:466: Fatal error.

Error reading main particle restart data.

End of stack

and if I deactivate in the GUI the choice for "different mesh", it works fine.

Let me know if you need more info.

Cheers,

Hello,

Sorry for not answering earlier.

The "restart on another mesh" feature currently handles only cell-based values, so does not yet work either with Lagrangian particles or ALE mesh deformation (based on vertex values).

We do need to add those features...
