DCID |
Curve identification number. No default (Integer > 0) |
ENDTYPEL |
Select from NATURAL, PARABOLIC, PERIODIC and CANTILEVER. See comment 1. Default = NATURAL |
LAMBDAL |
This parameter is only applicable for CANTILEVER type end condition. It should be left blank for other end conditions. A real valued parameter in the interval [0,1] that controls the left end condition for CUBIC spline interpolation. A value of 0 implies NATURAL end condition while a value of 1 implies PARABOLIC end condition. Default = 0.0 (0.0 < Real < 1.0) |
ENDTYPER |
Select from: NATURAL, PARABOLIC, PERIODIC and CANTILEVER. See comment 1. Default = NATURAL |

NSEG |
Number of segments used to visualize the deformable curve in animation. No default (Integer > 0) |
G1, G2, G3, … |
Ordered list of grid IDs defining the curve. |
Comments
1. | The deformable curve is generated using the CUBIC spline interpolation which requires assumptions on the second derivative of the interpolating function at either end of the curve. The keywords NATURAL, PARABOLIC, PERIODIC and CANTILEVER represent the four standard assumptions defined as follows: |
Note that λ =0.0 implies NATURAL (or free) end conditions and λ =1.0 implies PARABOLIC end conditions.
2. | This card is represented as a set in HyperMesh. |
