There’s a CCL only feature that allows you to attach a Monitor Point to a particular node. This is a beta feature that has been replaced with the Position Update Frequency option. More information about the Position Update Frequency option can be found in section 21.1.5.1.8.7. [Monitor Name]: Monitor Location Control, of the CFX-Pre User’s Guide in the ANSYS help documentation. The CCL for the old, beta method is: FLOW: OUTPUT CONTROL: MONITOR OBJECTS: MONITOR POINT: Monitor Point 1 Domain Name = Domain 1 Option = Vertex in Domain Vertex Number = 84634 Output Variables List = Total Mesh Displacement END END END END The Domain Name needs to match the name of the domain of interest. The variable of interest will often be Total Mesh Displacement, which will allow you to track the magnitude of the displacement of the selected node, but any variable can be entered. To find out a vertex (node) number at the point of interest, you can load the definition (.def) file into CFD-Post and then create a Point at the required XYZ location. After creating the Point, the nearest node number will be listed on the Geometry tab for the Point. If you don’t see this information then move the point slightly so that it lies within the mesh volume rather than on the mesh boundary.
