Question

Mapped Mesh doesn't work on a very simple part

Creo 9.0.7.0. T5 license

I'm trying to create a mapped mesh on very simple shape.  But when I try to create the mesh it fails to make bricks and reverts to tets.  I've spent a lot of time trying to do this very simple task and I am frustrated.

My geometry an extruded sketch.  It has (or had) some fillets on the vertical edges but I have suppressed them. I have selected every surface combination possible (there are 3 possibilities - top+bottom, the two sides, and the ID and OD).

I only have Creo Simulate Advanced 2 ( or 3).
Here is my model in Creo 2, does it work for you?

Thank you Skunks.  Your geometry was more complex than mine (you made a cone and I made a section of a cylinder) and you helped me think things through. 

 

The problem is that I applied a load using the "total load at point" option .  Which appears to be the only way to apply a force in a cylindrical coordinate system such that it can be analyzed using non-linear analysis.  My attempts to work around this problem have failed, but when I suppress this load it meshes.  Which makes sense - the mesher wants to put a node where I applied the force, but I randomly selected the point and it is not associated with any geometry and is not where a node is created by the mesher, so it creates a meshing conflict. I have since created a datum point (and a simulation point) in the geometric center of the face hoping that if the datum point was at the location of a node mapped meshing would work, but it doesn't.  I have determined why mapped meshing didn't work, but I have yet to overcoming the challenge of applying a load to the face (in a cylindrical coordinate system) so I can run the model non-linear.

 

This is preventing me from map meshing bricks:

    ..."total load at point"...

    For "total load at point", I would click on a corner point.
