Answer:
The general FE mesh settings can be modified using the IFeMeshSettings interface. This interface is located under IModel > IModelData > ICalculation. Image 01 shows which elements can be modified / displayed.
- Here is a code example where the target length of the FE elements is set to 100 mm. Furthermore, the division of the members with the same element size is activated and the minimum division is set to 3 elements:
Sub mesh_params()
Dim iApp As RFEM5.Application
' get interface for model data
Dim iModel As RFEM5.model
Set iModel = GetObject(, "RFEM5.Model")
On Error GoTo e
If Not iModel Is Nothing Then
' get interface for application and lock licence
Set iApp = iModel.GetApplication()
iApp.LockLicense
' get interface for model dat
Dim iModdata As RFEM5.IModelData2
Set iModdata = iModel.GetModelData
' get interface for calculation
Dim iCalc As RFEM5.ICalculation2
Set iCalc = iModel.GetCalculation()
' get interface for mesh settings
Dim iMeshSet As RFEM5.IFeMeshSettings
Set iMeshSet = iCalc.GetFeMeshSettings
' get general mesh settings
Dim meshGen As RFEM5.FeMeshGeneralSettings
meshGen = iMeshSet.GetGeneral
meshGen.ElementLength = 0.1
' set new general mesh settings
iModdata.PrepareModification
iMeshSet.SetGeneral meshGen
iModdata.FinishModification
' get mesh member settings
Dim meshMem As RFEM5.FeMeshMembersSettings
meshMem = iMeshSet.GetMembers
meshMem.DivideStraightMembers = True
meshMem.ElementLength = 0.1
meshMem.MinStraightMemberDivisions = 3
' set new mesh member settings
iModdata.PrepareModification
iMeshSet.SetMembers meshMem
iModdata.FinishModification
iApp.UnlockLicense
End If
e: If Err.Number <> 0 Then
MsgBox Err.description, , Err.Source
End If
iApp.UnlockLicense
Set iApp = Nothing
Set iModel = Nothing
End SubThe subroutine is also completed by an error interception routine (On Error GoTo e), and the Prepare-/FinishModification block is required, as in the case of modifying other elements. Here, the block is created via the IFeMeshSettings interface.
