Data description/conditions

Specification of location of external supports along pipeline axis (Input Table)

Data description/conditions:

REFIDENT:

Identification name of polygon point (n)

May be Undefined

(REFIDENT should come from table ORIGIN or POLYDIF or be generated by the program. If Undefined, see under Δ-AX-L.)

ΔAX-L:

Distance from polygon point along pipeline axis to (first) support

Required / May be negative

(A negative value means a distance back towards the origin. If REFIDENT is undefined, Δ-AX-L is the absolute AX-L value of the pipeline. The same counts for ΔX-P and ΔAX-LP)
(Column may be toggled to ΔX-P, ΔAX-LP, Δ Node, Δ Element or Identifier, see toggling data tables.)

COSYS:

Coordinate system in which the support acts

Prescribed names:Global, Local or Fixed Local

(Global: Support springs act in the overall coordinate (X-Y-Z) system
Local: Support springs act in the local node coordinate (x-y-z) system, which is turning with the pipeline axis.
Fixed Local: Support springs act in the Fixed local node coordinate (x-y-z) system, not turning with the pipeline axis.
See Coordinate systems for descriptions of the coordinate systems.)

SUPREF:

Support reference name

The specified name must be from the list in either table ELSPRS or table TFSPRS, else a function error occurs in Design Function 3.3.

SUPPLENG:

Length of support along pipeline axis

> 0. / Undefined

(The length will be subdivided into 2 support elements. If undefined, the support is assigned to one node without support angle: then the support force causes no ovalisation of the pipe.)

SUPANGLE:

Support angle

15. and ≤ 180. / Undefined ¹

(Must be undefined if SUPPLENG is undefined.)

ADDED:

Number of additional supports at a constant distance

> 0. / Undefined ¹

DISTANCE:

Distance between supports

> 0. / Undefined ¹
