    One can use:

    faceId = ExtAPI.SelectionManager.CurrentSelection.Ids[0] # Id of selected face in the UI
meshData = ExtAPI.DataModel.Project.Model.Analyses[0].MeshData # reference meshData
faceMesh = meshData.MeshRegionById(faceId) # get mesh data for face
faceMesh.ElementCount # get number of elements on face
faceMesh.NodeCount # get number of nodes
