    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

    Result Options

    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.
