Default Axisymmetric model

I am trying to model the heat transfer in a cylindrical annulus using an axisymmetric 2D model. I have a few questions reg. this.

1. I have read in the manual that the axis of rotation for axisymmetry should be the x-dirn, I have used this in my model but I want to know if its necessary or is there a way to change it to something else??

2. Once the results are generated, is there any way that I can regenerate the 3D model from this 2D axisymmetric model while postprocessing?? (something like reflecting it over the symmetry plane in case of 3D problems)

1) No you can't change it. You can define gravity in any direction you want though, so that does not matter. You can also rotate the view (Display->Views->Camera, and change the Up-Vector).

2) You can reflect the geometry about the axis of symmetry. That can also be done in the Display->Views Window.

Hope this helps, and good luck, Jason

Hi Jason

Thanks for the reply but I am not sure I have an axis of symmetry in my model.

The details of my model are these

1. I have a 2D rectangle, with the left edge aligned parallel to and 3.175 mm from the x-axis (the axis of rotation) defined as a wall with heat flux

2. the right edge defined as a wall with constant temperature

3. the top and bottom edges defined as walls with convection b.c.s

I need to maintain the distance of the left edge from the axis as I need to develop a circular hole of radius 3.175, once I regenerate the geometry in 3D.

Please let me know what can be done with this
