Mesh and periodic boundary condition in updated MOOSE

[mdh23rct]

Dear all,
I have updated MOOSE in HPC. I tried to run an input file in updated MOOSE. However, I am getting problem with the mesh and periodic boundary condition, although the file was running error free in the OLD MOOSE version.
The errors I am getting are attached here. The errors appear, when I use the periodic boundary condition:

''[BCs]
[./Periodic]
[./All]
auto_direction = 'x y'
[../]
[../]
[] ''

When I turn off the periodic boundary condition, the errors are gone. However, the simulation get stuck and does not move after Setting Mesh.....
The mesh definition I am using:
''[Mesh]
type = GeneratedMesh
dim = 2
nx = 50
ny = 50
xmin = 0
xmax = 80
ymin = 0
ymax = 80
uniform_refine = 2
elem_type = QUAD4
parallel_type = DISTRIBUTED
[]''

Any advice from your side, what is going wrong?

Thanks, and best regards.

Hello

There were some fixes in the periodic BCs about a year ago if I recall. The fix made sure the error came out correctly when the auto BCs were not being detected.

So I'm thinking the input likely did not work as expected before the update.

Can you try to set up the periodic BCs differently? With the other parameters not the auto ones

@GiudGiud I have tried running models which do not require any periodic boundary conditions. Still the simulation stays hanging in Setting Mesh.........
What I understood, there maybe a problem with the internal meshing tool of updated MOOSE. I believe the internal meshing tolerance is changed, which is creating difficulty to generate the mesh. My other colleagues are experiencing the same issue. I believe it would be wise if you can provide us with a guidline for meshing in MOOSE. Perhaps share it in the MOOSE website. Thanks.

Are you using conda to install moose?

Is this an "opt" build of moose?

How many processes are you using?
