In the figure below, choice of when an APDL Commands Object executes can be controlled if “Analysis Settings” contains more than one load step. When re-entering the /SOLU solution processor, a restart is required to continue from the most recent previous load step solution, rather than starting with a new analysis.Īn APDL Commands Object is shown in the above figure. Some changes between load steps can be based on solution information found in the /POST1 postprocessor. Under unusual circumstances, original coordinates of the active set of nodes might be modified according to solution values with the UPCOORD command. Element birth and death are supported with EALIVE and EKILL. Changes to real constants are possible with the RMODIF command. A user might choose to use commands that change a model between load steps, while a restart makes it possible to continue.Įxample changes between load steps include material changes with the MPCHG command. A single-frame restart makes it possible to inspect results in the /POST1 postprocessor, return to the solution processor, and continue in another load step. A simpler sort of restart, the single-frame restart, lets a user continue solving after the end of the most recent load step if Ansys has temporarily exited the /SOLU solution processor. Inside Workbench, multiframe restarts are employed for a variety of sophisticated purposes.

Details of a Single-Frame Restart in Workbench Mechanical Setup for a single-frame restart inside an APDL commands object in a Workbench Mechanical environment will be explored here. Other creative modifications could include material attribute changes (MPCHG) or Real constant adjustments (RMODIF). Modifications between load steps might perform EKILL or EALIVE commands that are based on element results after a SOLVE. Current documentation covers the multiframe restart, which lets a user restart an analysis from any saved load step or substep. A single-frame restart can make this possible.Īlthough no longer documented, it is still possible to perform single-frame restarts inside Ansys. When running Workbench Mechanical, a user might like to have APDL commands execute between load steps, going to the /POST1 processor to examine a model, make the kinds of changes permitted between load steps according to results examined, then go back to the /SOLU solution processor and continue with SOLVE for a next load step.
