Trying to apply BC on a mesh generated by gmsh

[AlexSacMorane]

Dear all,

I am a new user of Moose so I have a basic problem. Even if I have looked on the forum and on Moose documentation, my problem is staying here.
I try to study a diffusive problem on a mesh generated by gmsh but I have the following error problem.

*** ERROR ***
Task init_mesh is not registered to build MeshGenerator derived objects

Moreover, I have converted my .msh to a .vtu with meshio-convert and use this .vtu in my .i but I get a new error.

YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault (signal 11)
This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

I do not understand what happened here.

I stay available, thank for all the help you can give me.

Task init_mesh is not registered to build MeshGenerator derived objects means you are missing enclosing brackets on a mesh generator.

So you have something like

[Mesh]
  type = FileMeshGenerator

instead of

[Mesh]
  [fmg]
    type = FileMeshGenerator

Thank it helps.
I have changed a bit the simulation (I am now working on 2D). I have added the enclosing brackets. But I get again an error message.

*** ERROR ***
map_find() error: key "26" not found in file ../src/mesh/gmsh_io.C on line 605

Hello

Anything special about this mesh? What kind of elements does it contain?
I tried converting it to vtu to see what it looked like and I only saw an outer rectangular edge, no inside 2D elements?

Hello,

Thank you for your answer. I have rechecked my .msh file. You are right the mesh has disappeared. I have exported the .msh again and it seems it is working at this time. I do not understand why on the first try nodes were not exported.

Regards
Alexandre
