Answer:
The deformations of members can be read out using the "GetMemberDeformations()" function, for example. This function expects a number, the type of counting method for members (member number/number in the list), and which coordinate system should be used. You can select whether the local axis system, the principal axis system, or the global coordinate system is used:
Sub test_results_member_axis()
Dim iApp As RFEM5.ApplicationSet iApp = GetObject(, "RFEM5.Application")
iApp.LockLicense
Dim iMod As RFEM5.IModel3Set iMod = iApp.GetActiveModel
On Error GoTo e
'get interface for calculationDim iCalc As RFEM5.ICalculation2Set iCalc = iMod.GetCalculation
'get interface for resultsDim iRes As RFEM5.IResults2Set iRes = iCalc.GetResultsInFeNodes(LoadCaseType, 1)
'get deformations in local coordinate systemDim memDefs_L() As RFEM5.MemberDeformationsmemDefs_L = iRes.GetMemberDeformations(1, AtNo, LocalMemberAxes)
'get deformations in global coordinate systemDim memDefs_G() As RFEM5.MemberDeformationsmemDefs_G = iRes.GetMemberDeformations(1, AtNo, GlobalAxes)
'get deformations in principal coordinate systemDim memDefs_P() As RFEM5.MemberDeformationsmemDefs_P = iRes.GetMemberDeformations(1, AtNo, LocalPrincipalAxes)
e:
If Err.Number <> 0 Then MsgBox Err.description, vbCritical, Err.Source
iMod.GetApplication.UnlockLicenseSet iMod = Nothing
End Sub
The small program reads out the local deformations (memDefs_L) in the member axes and the principal axes (memDefs_P) and the global deformations in the member axes (memDefs_G).
