QUESTION:
User wants to be able to manually control the OSLM and override the defaults set by SOLCONTROL. When SOLCON is on and TINTP is used to adjust the oscillation limit, ANSYS echoes (output file or window) that the new OSCL setting is accepted. However, it is not being used during solution (the default gets used instead).
ANSWER:
The workaround is to disable SOLCON, do NOT use OPNCONTROL, but turn on AUTO TIMESTEPPING:
