Changing dimensions programmatically and running simulations

Hello All,
This might be a novice question, but I have been trying to find an answer to it for sometime now without luck.

As an example, let us consider a bending cylinder. I'm currently importing my geometry into ANSYS Workbench 18.2 from my Inventor 2016 with certain dimensions labeled as parameters (DS_length, DS_diameter, etc.).

I wish to run several iterations of the simulation with one end of the beam fixed, the parameters modified a little, and record the displacement of the tip of the beam.

Is this possible to do in workbench with a set of APDL commands? I already have the commands to extract the location of the beam tip at the end of a single iteration. But I'm looking to run several iterations of the same with parameters modified.

I'm sure there's a set of tutorials online that I'm missing, that explains how to do this, but I was unable to locate the same. Therefore, I thought it would be nice to have a forum post with a collection of links to do the same.

Thank you.

I use SIEMENS NX11 and learned how to import parameters into Workbench. Many people use SOLIDWORKS, and I figured out how to import parameters into Workbench from there too. However, no one on a Student license can benefit from this because the Student license does not include the associative CAD interface required to allow parametric updates to work.

Everyone has SpaceClaim, so it could be helpful to show how to add parameters to imported geometry for use in a Parameter Set design study in Workbench. I often find that the feature history used to create the shape of the part in the original CAD system is cumbersome when you want to study some shape parameters in Workbench. When I import geometry into SpaceClaim, all the feature history is gone, and I can move faces in SpaceClaim, while adding the move distance as a Parameter, so this capability may be preferred even by people with the associative CAD license.
