Mesh Question

[Dave442]

I am new to Ansys and apologise if this is a stupid question, however I could use some help!

I am trying to model a cardiovascular stent (a small wire mesh tube) and plan to:

1) Model and mesh the stent in a cartesian coordinate system based on the "rolled-out" stent geometry

2) Map the stent into its cylindrical configuration by geometrical transformation of nodal coordinates.

This appears to be the process that is generally used in the literature of FE analsysis of stents.

My problem is I do not understand how to transform the nodal coordinates from their rectangular shape into a cylindrical shape.

If anyone could provide some insight it would be greatly appreciated!

Thanks!

Hi... you can check out the command 'clocal' from the Help file of Ansys to transform into a polar coordinate system.

Check ANSYS help for coordinate system..
