SapObject.SapModel.Results.LinkForce
Function LinkForce(ByVal Name As String, ByVal ItemTypeElm As eItemTypeElm, ByRef NumberResults As Long, ByRef Obj() As String, ByRef Elm() As String, ByRef PointElm() As String, ByRef ACase() As String, ByRef StepType() As String, ByRef StepNum() As Double, ByRef P() As Double, ByRef V2() As Double, ByRef V3() As Double, ByRef T() As Double, ByRef M2() As Double, ByRef M3() As Double) As Long
Name
The name of an existing link object, link element, or group of objects ,depending on the value of the ItemTypeElm item.
ItemTypeElm
This is one of the following items in the eItemTypeElm enumeration:
ObjectElm = 0
Element = 1
GroupElm = 2
SelectionElm = 3
If this item is ObjectElm, the result request is for the link element corresponding to the link object specified by the Name item.
If this item is Element, the result request is for the link element specified by the Name item.
If this item is GroupElm, the result request is for all link elements directly or indirectly specified in the group specified by the Name item.
If this item is SelectionElm, the result request is for link elements directly or indirectly selected and the Name item is ignored.
For GroupElm and SelectionElm a link element may be indirectly specified through point objects that have panel zone assignments and through line, area and solid objects that have spring assignments.
NumberResults
The total number of results returned by the program.
Obj
This is an array that includes the link object name associated with each result, if any.
Elm
This is an array that includes the link element name associated with each result.
PointElm
This is an array that includes the point element name associated with each result.
ACase
This is an array that includes the name of the analysis case or response combination associated with each result.
StepType
This is an array that includes the step type, if any, for each result.
StepNum
This is an array that includes the step number, if any, for each result.
P
This is an array that includes the link axial force (in the link local 1-axis direction) at the specified point element. [F]
V2, V3
These are one dimensional arrays that include the link shear force components in the link element local axes directions. [F]
T
This is an array that includes the link torsion (about the link local 1-axis) at the specified point element. [FL]
M2, M3
These are one dimensional arrays that include the link moment components about the link element local axes. [FL]
This function reports the link forces at the point elements at the ends of the specified link elements.
The function returns zero if the forces are successfully recovered, otherwise it returns a nonzero value.
See Analysis Results Remarks for more information.
