This use case shows you how to create Advanced surface mesh part on an existing analysis document. This scenario requires "FEM Surface (FMS)" product.
This macro opens an existing Analysis document. Advanced surface mesh part is created and global specifications associated with this mesh part are set. The local specification: MSHDistributionElement is created around the edge of the hole. The mesh part is updated to generate mesh.
CAAAniMeshAdvSurf is launched in CATIA [1]. No open document is needed.
CAAAniMeshAdvSurf.catvbs is located in the CAAScdAniUseCases module. Execute macro (Windows only).
CAAAniMeshAdvSurf includes the following steps:
- Prolog
- Extracting the List of Mesh Parts and Publications
- Creating Mesh part and Assigning Values to its Attributes
- Epilog
Prolog
... ' -----------------------------------------------------------
' Optional: allows to find the sample wherever it's installed
sDocPath=CATIA.SystemService.Environ("CATDocView")
If (Not CATIA.FileSystem.FolderExists(sDocPath)) Then
Err.Raise 9999,,"No Doc Path Defined"

Open the Analysis document. The Analysis document is retrieved in the
documentation installation path, this path has already been stored in the
sDocPath variable. In the collection of documents, two documents
can be retrieved; the Analysis document and the Part document.
Extracting the List of Mesh Parts and Publications
... 'Retrieve the Analysis Manager and Analysis Model Set oAnalysisManager = oAnalysisDocument.Analysis 'Retreive the part document from Analysis manager Set oAnalysisLinkedDocument = oAnalysisManager.LinkedDocuments Set partDocument = oAnalysisLinkedDocuments.Item(1) Set product = partDocument.Product 'Retrieve the analysis model from the list of models Set oAnalysisModels = oAnalysisManager.AnalysisModels Set oAnalysisModel = oAnalysisManager.Item(1) 'Retrieve mesh manager and mesh part Set oAnalysisMeshManager = oAnalysisModel.MeshManager Set oAnalysisMeshParts = oAnalysisMeshManager.AnalysisMeshParts
'Retrieve publications from product and retrieve the published surface and edge
Set publications1 = product.Publications
Set pubEdge = publications1.Item("Edge")
Set pubSurf = publications1.Item("Round Hole.1")

According to the general Analysis Document structure, this macro uses some standard procedures to navigate or retrieve the required objects. First, from the Document, we find the Analysis Manager Object, the Analysis Models and the Mesh Manager Objects. The extraction of pre-defined geometric elements is done by using the Reference interface. This is equivalent to the selection of a B-Rep element inside the interactive application. Here the reference is created from a published face.
Creating the Mesh Part and Assigning Values to its Attributes.

'Add the new Advanced surface mesh part to the list of mesh parts
Set surfPart = meshParts.Add ("MSHPartSmartSurf")
'Add support from the published surface surfPart.AddSupportFromPublication product, pubSurf 'Set the global

Here parameters are set with their respective units, this helps in setting up of the parameters independent of the unit settings. Calling update on the mesh part computes the mesh.
Epilog

To run the macro interactively CATDocView environment variable must be defined.
