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 dataDim iModel As RFEM5.modelSet 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.UnlockLicenseEnd 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.
