panel set twindow_function dy
The DY function returns the y-component of the translational displacement vector from J_MARKER (i2) to I_MARKER (i1), as expressed in the R_MARKER (i3) coordinate system. J_MARKER (i2) may not be specified, in which case, it defaults to ground. Similarly, the R_MARKER (i3) may not be specified, in which case it defaults to ground. Mathematically, DY is calculated as follows:
DY = [ Ri1 - Ri2] yi3
where, Ri1 is the displacement of marker i1 in ground, Ri2 is the displacement of marker i2 in ground, and xi3 is the unit vector along the y-axis of marker i3 .

Description:
Parameter | Value Type | Description |
|---|
I_marker_name | Existing Marker | Specifies an existing marker used as the I_MARKER (i1) in the evaluation of the function. |
J_marker_name | Existing Marker | Specifies an existing marker used as the J_MARKER (i2) in the evaluation of the function. |
R_marker_name | Existing Marker | Specifies the marker used as the R_MARKER (i3) with respect to which you want Adams to evaluate the function. If you do not supply this parameter, Adams will evaluate the function in the ground reference frame. |
Extended Definition:
1. You may identify a marker by typing its name or by picking it from the screen.
If the marker is not visible on the screen, you must type the name.
You may also find it convenient to type the name even if the marker is displayed.
If you created the marker by reading an Adams data set or graphics file, the marker name is the letters MAR followed by the Adams data set marker ID number. For example, the name of Adams MARKER/101 is MAR101. If you created the marker during preprocessing, you will have given it a name at that time.
If a marker is available by default, you may identify it by entering only its name. If it is not, you must enter its full name. To identify a marker under a different part, for instance, you may need to enter the model and part names as well. For example, you may specify marker 'pivot' from model 'links', part 'lower_arm' by entering ".links.lower_arm.pivot". If you type a "?", Adams View will list the markers available by default.
You must separate multiple marker names by commas.
If the marker is visible in one of your views, you may identify it by picking on it.
You need not separate multiple marker picks by commas.
