The tutorial copied from the link below can not be excuted.
https://develop.openfoam.com/Develop...aceMountedCube

The problem is that the solver stops before time 0, neither continuing nor throwing error message

I tried to debug with following tests:
a. decrease the mesh resolution by twice
b. increase viscosity, decrease Reynolds number by ten times
c. add finite volume option
d. try different solver pimpleFoam and pisoFoam
e. try different LES model like Smagorinsky, spalartAllmaras and QR(developed by our group)

The result doesn't change, the solver still stops before time 0, neither continuing nor throwing error message

works fine for me. maybe post your full case here. I'm suspecting issue comes from your parallel setting.
