A crack-growth simulation can be time-consuming, and the results may not meet your expectations even after a successful first run. The multiframe-restart capability for SMART-based analysis enables you to restart the analysis and continue the simulation from the previous run.
You can resume a crack-growth analysis from any load step or substep. You can therefore resume a job from the end of the previous run or from some intermediate time point. You can also recover a job from an abnormal termination.
Due to the number of restart files that Mechanical APDL is able to store from prior runs, you
can only restart an analysis at a substep for which the corresponding
.rnnn, .rdb, and
.ldhi load-history files exist. (To specify the frequency at which
restart files are written, see RESCONTROL.)
After selecting a substep from which to restart the crack-growth analysis, see ANTYPE,,RESTART to perform the restart operation. For more information, see Multiframe Restart in the Basic Analysis Guide.
SMART Multiframe Restart Requirements and Limitations
SMART-based static crack-growth and fatigue crack-growth analyses are supported.
SMART crack-growth analysis supports a SMP or DMP configuration. Do not change the number of cores in a DMP configuration when restarting a SMART crack-growth analysis.
Nonproportional loading and complex spectrum loading defined via CLOAD are not supported.
