I would like to utilize SimulationXpress to analyze the stresses on a rotating pipe. I can calculate the radial (centrifugal) force and apply it on the inside wall with a radially outward vector, also calculate the hoop force though to apply the force vector would require a cylindrical coordinate system - which I am having trouble locating in SW and the axial force at the moment is not of interest.

Does SW have a tutorial rotating structures which I may have missed?

Thank you

Most folks would use the full version of SOLIDWORKS Simulation instead of SOLIDWORKS SimulationXpress for something like this because:

1. In SOLIDWORKS Simulation, you can view a plot with a cylindrical coordinate system directly under Edit Definition > Advanced Options > Plane, Axis or Coordinate System > [Select Axis]:

2. Centrifugal loads are "body loads" and therefore it is more accurate to apply such a load per element rather than approximating it as a force on a face. The full version of SOLIDWORKS Simulation (even the most basic package that comes with a license SOLIDWORKS Premium) allows you to directly apply a centrifugal load.

Here are some additional references that may be useful:

A. SOLIDWORKS Knowledge Base (KB) solution S-074771:

"Is there a simple example that shows how to use SOLIDWORKS® Simulation to extract circumferential "hoop" stress in the tangential direction of a thin cylinder?"This KB solution includes the sample model in the image above (including a ready to run SOLIDWORKS Simulation Static study).B. The SOLIDWORKS Simulation Professional Training Course covers the more advanced topic of frequency analysis of a rotating part. For reference, the training files for this course are available here. Of particular interest is the impeller with centrifugal load frequency study file (Impeller 01.sldprt).

I recommend reaching out to your SOLIDWORKS Value Added Reseller (VAR) for additional information.
