VB6 Procedure

Function SolidStress(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 LoadCase() As String, ByRef StepType() As String, ByRef StepNum() As Double, ByRef S11() As Double, ByRef S22() As Double, ByRef S33() As Double, ByRef S12() As Double, ByRef S13() As Double, ByRef S23() As Double, ByRef SMax() As Double, ByRef SMid() As Double, ByRef SMin() As Double, ByRef SVM() As Double, ByRef DirCosMax1() As Double, ByRef DirCosMax2() As Double, ByRef DirCosMax3() As Double, ByRef DirCosMid1() As Double, ByRef DirCosMid2() As Double, ByRef DirCosMid3() As Double, ByRef DirCosMin1() As Double, ByRef DirCosMin2() As Double, ByRef DirCosMin3() As Double) As Long

Parameters

Name

The name of an existing solid object, solid 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 solid elements corresponding to the solid object specified by the Name item.

If this item is Element, the result request is for the solid element specified by the Name item.

If this item is GroupElm, the result request is for the solid elements corresponding to all solid objects included in the group specified by the Name item.

If this item is SelectionElm, the result request is for solid elements corresponding to all selected solid objects and the Name item is ignored.

NumberResults

The total number of results returned by the program.

Obj

This is an array that includes the solid object name associated with each result, if any.

Elm

This is an array that includes the solid element name associated with each result.

PointElm

This is an array that includes the name of the point element where the results are reported.

LoadCase

This is an array that includes the name of the analysis case or load combination associated with each result.

StepType

This is an array that includes the step type, if any, for each result. See 
Analysis Results Step Type
.

StepNum

This is an array that includes the step number, if any, for each result.See 
Analysis Results Step Number
.

S11, S22, S33, S12, S13, S23

The solid element internal S11, S22, S33, S12, S13 and S23 stresses at the specified point element location, reported in the solid element local coordinate system. [F/L
2
]

SMax, SMid, SMin

The solid element maximum, middle and minimum principal stresses at the specified point element location. [F/L
2
]

SVM

The solid element internal Von Mises stress at the specified point element location. [F/L
2
]

DirCosMax1, DirCosMax2, DirCosMax3

These are three direction cosines defining the orientation of the maximum principal stress with respect to the solid element local axes.

DirCosMid1, DirCosMid2, DirCosMid3

These are three direction cosines defining the orientation of the middle principal stress with respect to the solid element local axes.

DirCosMin1, DirCosMin2, DirCosMin3

These are three direction cosines defining the orientation of the minimum principal stress with respect to the solid element local axes.

Remarks

This function reports the stresses for the specified solid elements. Stresses are reported at each point element associated with the solid element.

The function returns zero if the stresses are successfully recovered, otherwise it returns a nonzero value.

See Analysis Results Remarks for more information.
