Hi,
Sorry if this has been answered. I am trying to figure out if there is a way to globally refine the mesh in AutoPIPE in static analyses without adding more points. My understanding is no as 'element' size is the distance between two points. Is this correct? I know for soils you specify a soil point spacing but I could not find anything like this for regular piping. Thanks!

Good day to you Taylor,
As mentioned on General Information WIKI here:
Bentley AutoPIPE like all other stress programs uses 1-D finite elements which use simple Beam element center-line based theory, also known as the stiffness or displacement method, to mathematically model the piping system in three dimensional space.....
With that said, you now know that the program does not have a mesh settting. The only options is to manually add additional node points in the model or as mentioned by Pawel, update the aforementioned setting.

Hi Josh,
I wanted to understand your use case and the need for having an option which could insert intermediate nodes automatically. Intermediate stress points is able to divide a section of pipe up in to multiple points, use empirical formulas to get the value of forces and moments at these intermediate points, and calculate stresses using these forces and moments.
What is your specific requirement and how would such automatic intermediate points help you? What would be the criteria that you have in mind which would generate these points automatically? For example, for automatic mass points in AutoPIPE - we divide a span based on the optima length required to capture dynamic behavior. If we have a strong use case which other users would also be interested in, we could consider adding it to the program.
