Axisymmetric model

Hi

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)

Thanks

Satish

Re: Axisymmetric model

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

Re: Axisymmetric model

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
