Example 
using (Transaction trans = new Transaction(doc, "AddAssociationBetweenPhysicalAndAnalyticalElements"))
{
   trans.Start();

   ElementId idAnalyticalElem = GetSelectedObject(activeDoc, "Please select analytical element");
   ElementId idPhysicalElem = GetSelectedObject(activeDoc, "Please select physical element");

   //gets the AnalyticalToPhysicalAssociationManager for the current document
   AnalyticalToPhysicalAssociationManager analyticalToPhysicalManager = AnalyticalToPhysicalAssociationManager.GetAnalyticalToPhysicalAssociationManager(doc);
   if (analyticalToPhysicalManager == null)
      return Result.Failed;

   //creates a new association between physical and analytical selected elements
   analyticalToPhysicalManager.AddAssociation(idAnalyticalElem, idPhysicalElem);

   trans.Commit();
VB 
Using trans As Transaction = New Transaction(doc, "AddAssociationBetweenPhysicalAndAnalyticalElements")
    trans.Start()
    Dim idAnalyticalElem = GetSelectedObject(activeDoc, "Please select analytical element")
    Dim idPhysicalElem = GetSelectedObject(activeDoc, "Please select physical element")

    'gets the AnalyticalToPhysicalAssociationManager for the current document
    Dim analyticalToPhysicalManager = AnalyticalToPhysicalAssociationManager.GetAnalyticalToPhysicalAssociationManager(doc)
    If analyticalToPhysicalManager Is Nothing Then Return Result.Failed

    'creates a new association between physical and analytical selected elements
    analyticalToPhysicalManager.AddAssociation(idAnalyticalElem, idPhysicalElem)
    trans.Commit()
