A strange bug during coupled pore pressure dissipation

Hi Itascan, Please see below two screen-shots, the top one with “time-total = 86400” which is working properly, while for the bottom one with “time-total = 8640”, only one mechamical substep will be executed for every flow step, regardless of mechnical convergence. Looks like when the “time-total” is less than a certain value, FLAC3D is not working properly. I believe this is bug.

I would suggest you send the datafile to Itasca for an investigation.
