CUBSPL(x,z,id) or CUBSPL(x,0,id, n)

Description

Returns the interpolated value or n-th derivative of the interpolated value of Reference_Spline element.

Example

<Force_Scalar_TwoBody

  id             = "301001"

  type           = "Force"

  i_marker_id    = "10506"

  body1_id       = "105"

  j_marker_id    = "10706"

  body2_id       = "107"

  val_expression = "CUBSPL(DM(10503,10703),0,301002)"

/>

<Reference_Spline

   id            = "301002"

   num_xy_pair   = "5"

   linear_extrap = "FALSE">

                   0.0000000E+00  -2.2000000E+02

                   2.0000000E+02  -2.2000000E+02

                   2.3000000E+02  -2.2000000E+02

                   3.7322400E+02  -1.1000000E+02

                   5.0000000E+02  -1.1000000E+02

</Reference_Spline>

Arguments

x

The independent variable of the curve.

z

The independent variable z of the surface. Use z=0 if only one curve is being defined.

id

The ID of the Reference_Spline element.

n

The order of the derivative desired. Not applicable with surfaces. Must lie between 0 and 2.
