panel set twindow_function dm
The DM function returns the magnitude of the translational displacement vector from J_MARKER (i2) to I_MARKER (i1).
Format:
panel set twindow_function dm |
|---|
i_marker_name = | an existing marker |
j_marker_name = | an existing marker |
Example:
panel set twindow_function dm & |
|---|
panel set twindow_function dm i_marker_name = | marker_71 & |
panel set twindow_function dm j_marker_name = | marker_82 |
Description:
Parameter | Value Type | Description |
|---|
i_marker_name | AN EXISTING MARKER | Specifies an existing marker used as the I_MARKER (i1) in the evaluation of the function. |
j_marker_name | AN EXISTING MARKER | Specifies an existing marker used as the J_MARKER (i2) in the evaluation of the function. |
Extended Definition:
1. The J_MARKER (i2) may not be specified, in which case it defaults to ground. DM is the distance between markers i1 and i2 and by definition is always positive. Mathematically, DM is calculated as follows:
DM = ( [ Ri1 - Ri2] [ Ri1 - Ri2] )**1/2
where Ri1 is the displacement of marker i1 in ground, and Ri2 is the displacement of marker i2 in ground.
2. 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. The name of ADAMS MARKER/101 is MAR101, for example. If you created the marker during preprocessing, you gave it a name at that time.
If a marker is available by default, you may identify it by entering its name only. 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.

Tips:
1. You need not separate multiple marker picks by commas.
