5 Analyze the Simulation
Module Overview
Obtaining analyses data from a simulation is one of the most valuable aspects of using simulation
as part of the manufacturing process. The data obtained in these analyses can be captured and
generated into reports that feed multiple decision making processes. The power of the PPR
architecture is that it permits easy revision of the simulation model based on the outcome of the
analyses by permitting direct access to the data through the PPR tree.
The value of Dynamic Clash was demonstrated in an earlier module. Now, with the Clash analysis
functionality fully engaged, the clash information can be captured and generated into an XML
report.
Distance and Band analyses provide important information regarding part fit through the
measurement of distances and graphical representation of the seed distance between two parts.
Sectioning allows the user to" see inside” a slice of the assembly, giving a unique perspective that
can sometimes answer some sticky manufacturing questions. This information, is captured and
can be reported.
With Swept Volume, the total amount of space that is necessary to accomplish a move is visualized.
So, while a trajectory of a move may appear to be adequate, swept volume can uncover clues to
the physical space necessary that may not be apparent otherwise.
In Measure Analysis the model can be queried for specific measurements. Measuring an item, its
thickness, and the distance between it and another object, reveals critical information for
manufacturing, tooling, human and a variety of other factors.
The Gantt Chart allow the user to see the larger picture of the simulation study. It represents the
sequence of activities and the impact of time. As with the other functions, modifications made
to the process or properties in the Gantt chart are reflected throughout the simulation.

About Collision Analysis
Conduct
Collision
Analysis
Earlier, Dynamic clash detection was used to get a general idea of the intended moves when
creating a simulation. This topic describes how to use Clash Detection when bodies are static
and when a move activity is executed. This clash methodology is capable of analyzing the
clash situation, capturing the data, and producing reports that assist with project
communication.
Running the simulation in assembly or disassembly
sequence with the stop mode activated will cause the
simulation to stop at every occurrence of a clash.
This offers an overview of existing conditions.
When Clash Checking is activated its parameters can be
set to examine interference in a variety of ways. The
analysis can be configured as the clash is examined
or, a queue can be established ahead of time that
forms a list of specific items to be analyzed. When
the analysis is configured, the ability to conduct a
Bind analysis is activated.
Producing XML reports of clash conditions
captures the information for discussion
and is easily shared in many media forms.
More about Clash Detection can be found in
the On-Line documentation

Run the Simulation in Stop mode - Procedure
Conduct
Collision
Analysis
Running the simulation with Clash Detection in Stop Mode gives a general picture of the
clash locations.
1 Begin running a clash analysis by restoring the initial
state of the simulation.
By using the Reverse the Process function, the
simulation can be evaluated for clash
conditions in either assembly or disassembly
sequence.
2
From the Simulation Analysis toolbar select the Clash
Detection drop down to reveal the Clash Modes Off, On
and Stop. Select the Stop mode. This will stop the
simulation at every occurrence of a clash.
3 Run the simulation. Use the Process Simulation player to step through the simulation as
it stops at each clash.

Clash Checking - Procedure
Conduct
Collision
Analysis
Activating Clash Analysis creates the ability to examine and collect clash data in a
variety of ways.
1 Activate Clash Analysis by clicking on the Clash icon in the
Simulation Analysis toolbar.
2
The Check Clash dialog box appears. Name the Analysis with some unique identifier then
select the type of analysis desired.
Contact + Clash
Checks for contact as well
as any overlapping
space.
Authorized penetration
Checks whether an object
penetrates another
object beyond a
specified amount.
Penetration distance is
set in the specification
box.

Clearance + Contact + Clash
Checks for contact, overlapping space, and

zone around an object or objects.
Clearance values are set in the
specification box.
Clash rule
Checks whether the situation is in conformance with a
previously established rule.

or the Penetration
depth depending
on the type of
analysis selected.
