panel set acf_twindow dynamic_simulation
Specifies the type of analysis you want Adams to perform is dynamic.
The DYNAMIC_SIMULATION command specifies that Adams is to integrate the dynamics equations. If you request a dynamic analysis for a model with zero degrees of freedom, Adams issues a warning message and integrates the equations instead of using kinematic analysis.
Kinematic analysis is faster.
You may use the 'MODEL VERIFY' command to display the number of degrees-of-freedom in your model.

Description:
Parameter | Value Type | Description |
|---|
number_of_steps | Integer | Specifies the number of values to be stored in each component of a result set being read from a file. |
step_size | Real | Specifies the size of the output step for a dynamic, kinematic, or quasi-static equilibrium analysis in model time units. STEP_SIZE must be greater than zero. |
end_time | Real | Specifies the end time for a dynamic, kinematic, or quasi-static equilibrium analysis. |
duration | real | Specifies the duration for a dynamic, kinematic, or quasi-static equilibrium analysis in model time units. The DURATION must be greater than zero. |
Extended Definition:
1. All components being read from a file must have the same number of steps. Lines that do not begin with a number are considered comments and ignored.
If the parameter “number_of_steps” is not specified the size of the components will be inferred from the format of the file. A component will be read from a file until a comment line is encountered. This commented line marks the end of the component.
2. The parameter END_TIME must be greater than the begin time. Since the begin time must be greater than zero, this means that the end time must also be greater that zero.
