Drop Test - Study Load Simulation: Tools Add-Ins, check the box
click on Drop Test
and name the file
Simulation creates two
folders: Setup and

Drop Test Setup Folder
Right click the
Setup folder and
select Define/Edit
Specify drop
height or velocity
at impact.
Vimpact = (2gh)1/2
Sets the height from which
the body is dropped from rest
Target: sets the orientation of
the impact plane
Normal to gravity. The impact plane is normal to gravity.
Parallel to Ref. plane. The impact plane is parallel to the
selected reference plane.
Target orientation reference. Select a reference plane
Sets the direction and value of
the acceleration of gravity

Drop Test Result Options Folder
Right click the
Result Options
folder and select
Define/Edit
Sets the time to monitor what happens
to the object during the first 106
microseconds after the first impact.
Sets the time to start saving results.
The default value of 0 instructs the
program to start saving data from
the moment of first impact
Number of Plots, accept the default
25, this means that the solution is
divided into 25 intervals and the
results (plots) are saved for these
intervals only.
Select points (vertices), results
for these points will be available
in the time history plots
No. of graph steps per plot, Sets the number of graph intervals for result plots.
The total number of data points for each graph is equal to No. of plots times No.
of graph steps per plot.
