Hi, I'm running an FSI simulation coupling CFX with Mechanical, and one of the monitor points I set is the Total Mesh Displacement of an specific mesh node.

The problem is that, to set this monitor, I need to know the node number of that node. But I don't really know an easy way to find it (I searched through the documentation and find nothing about this). I discovered that I can set a point to a node number at CFD-Post, so I used this to find a node nearby the region I needed, but this is very impractical as I had to set the point to multiple points until I found one that suits me, and if I change the mesh I would need to do this again. Is there an easier way to find it? Or an easier way to get the Total Mesh Displacement of an specific point of the mesh?

Can't you define a monitor point by x,y,z location, and use the nearest node option? Then select the option for the monitor point to move with the mesh and you can get the displacement of that mesh node without ever knowing what the node number is.
Opaque and Ashkan Kashani like this.

You can display node and cell numbers in Tecplot.
In Tecplot, follow Plot >> Label Points and Cells and then check Show node labels and Show cell labels.
I am not aware of any other method to do that.

Yes, defining the monitor point by coordinate solves my problem! Thank you for the answer. I only had to set the Position Update Frequency to "Initial Mesh Only" so that the node doesn't change during the simulation.
