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.
