Performing Drop Test Analysis
To perform a drop test study:
Create a drop test study. Right-click the top
icon in the Simulation study tree and select Study
to access the Study
dialog. Define the Properties of the study to select a small or large
displacement formulation. Large displacement solution takes much longer
time but is more accurate. Large displacement is used by default for linear
materials and it is always used if you have a nonlinear material in the
model.
You can perform drop test
analysis on solid parts and assemblies only. Shells are not supported.
Setup the study. Right-click the Setup
icon and select Define/Edit.
Define result options. Right-click the Result
Options folder and select Define/Edit
to specify solution time parameters and locations at which response versus
time graphs will be available after running the study.
For assemblies and multibody parts make sure to
define the proper contact settings.
Mesh the model and run the study.
When the drop test starts running, the program
generates extra contact elements around the model surfaces. These contact
elements, which are based on the mesh information, are used for contact
analysis during the drop-test solution. The contact elements increase
the number of nodes and elements of the original mesh. The solver dialog
reports the updated mesh information.
If you run a study before
meshing it, the program meshes the study automatically before running
it. You can also request to run the study by checking Run
analysis after meshing in the Mesh
PropertyManager. Running a drop test study can take a long period
of time due to intense computations.
View results:
Double-click
an icon in a results folder to display the associated plot.
To define a new plot, right-click the Results folder and select the desired
option. You can plot stresses, strains, displacements, and deformation.
To list results, right-click the Results
folder and select the desired option. You can list stresses, strains,
displacements, and contact/friction forces.
To define a time history graph, right-click
the Results folder and select
Define Time History Plot. You
can graph stresses, displacements, velocities and accelerations.
To generate a report, right-click the Report folder and select Define.
To probe an active plot, right-click its icon
or right-click in the graphics area, and select Probe.

When you run a study that
does not have any result folders, the software creates the folders and
plots specified in the Result
Options for the study type. If result folders are present,
the software updates the existing plots.
