Hi there, thank you for using the forum!
In contrast to the simulation, the meshing progress has discrete phases, and it is likely that it will go from 0% to an intermediate phase, and then straight to 100%. If the estimation was around 48 minutes, it is likely that it will jump from 0% to a higher value soon, In any case, make sure to check the meshing log for more information about the progress.
Best regards,
