ANSYS Explicit Dynamics Explicit Dynamics: Analysis Settings

• Analysis Settings are grouped in six categories
– Step Controls
– Solver Controls
– Damping Controls
– Erosion Controls
– Output Controls
– Analysis Data Management
• Specifies directory where project data will be stored
• End Time is the only required input
– All other options have defaults

Solve Initiation

– Resume From Cycle

• Specifies the cycle (time step) from which to start the Solve.

– Default (cycle 0) is to start at the beginning (time zero).

• When resuming a simulation, changes to analysis settings will be

respected where possible.

– e.g. you often wish to resume a simulation with an extended End Time.

• Changes to any other features in the model (geometry

suppression, connections, loads, etc….) will not be respected.

• List of cycles from which to resume will only be populated if a

previous solve has been executed and restart files generated.

• Solve Termination

– Maximum Number of Cycles

• Specifies the maximum number of cycles (time increments)

allowed for the simulation.

– The simulation will stop once the specified value is reached.

– Enter a large number (default) to ensure simulation runs to the End

Time.

– End Time (no default)

• Defines the timescale that you want the simulation to run.

• Enter a reasonable estimate for this parameter since it controls the

length of time the simulation will take to run.

• Used in other pre-processing objects (such as tabular loads) and

also to define the scale for Chart output of results objects.
