Node number update

[SM1994]

Dear all
I am using python to generate a shape that the thickness and mesh size of it and hence the node number of it changes by each job.
I want the displacement of a specific part of geometry (attached), but I`d prefer to find a code or a solution that Abaqus automatically find the path for each job.
at the moment I manually select the nodes to create a path, but I want to find a way that code finds the nodes and creates that path automatically.
Thanks

Path can be also defined based on point coordinates (these are independent of the mesh density). To create a path with Python script you just have to use session.Path object and specify type as well as the list of nodes/points.
