DM

The DM function computes the magnitude of the total relative translational displacement between two markers.

Format

DM(I, J)

Description

The first argument, marker I, must be specified. The second argument, marker J, is optional.

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.

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)"
