DM(I, J)

Description

The DM function computes the magnitude of the total relative translational displacement between two markers.  The first argument, marker I, must be specified.  The second argument, marker J, is optional.

Example

<Force_Scalar_TwoBody

    id                  = "31001"

    type                = "Force"

    i_marker_id         = "31001010"

    body1_id            = "30401"

    j_marker_id         = "31001011"

    body2_id            = "30501"

    val_expression      = "IMPACT(DM(30401010,30501010),VM(30401010,30501010),10,2000,1,0.05,0.01)"

Arguments

I

The marker whose displacement is to be computed.

J

The marker with respect to which the displacement is to be computed.  This argument is optional.  If omitted, it defaults to the ground coordinate system.
