4.8.3.97. RD_UCF

The RD_UCF subroutine returns UCF (Unit correlation factor).

UCF is defined as UCF * 1.0 [F] = 1.0 [ML/T^2].

Language type	Subroutine
FORTRAN	call rd_ucf(ucf)
C/C++	rd_ucf(&ucf)

Table 4.240 Parameter information

Variable Name	Size	Description
ucf	double	The output variable, The unit of the output of the force type must be used [F] unit.

Note

The units are used [N], [kg], [mm], and [s]. The UCF is always 1000.0. ( 1[N] = 1000 [kg*mm/s^2] )

The unit of the output of the force type USUB functions must be used [F] unit. If user uses the [MLT^-2] force unit, then output force vectors needed to multiply the 1/UCF value.
