danobis, here is a working example of a journal files (.jou), when you see a ";", it means i'm asking fluent to skip that command:

The TUI command “ solve/iterate 100” just iterates 100 more iterations. This is used for running steady simulations.

Use the following commands for running a transient simulation:

solve/set/time-step 1e-2 ( for setting the time step size)

solve/dual-time-iterate 100 40 ( 100 is the number of time steps and 40 is the iterations per time steps)

The periodicity (set under Mesh (tab) => Global Parameters) is to ensure that your mesh on one side matches the mesh on the other side... Once you see the DEZ (data entry zone), you will understand what you need to fill in. Periodicity is set on the geometry so that the generated mesh comes out periodic, so if you go back to set it, you must regenerate.

Even if you are copying your mesh around to create an annulus instead of a periodic section, it will be easier if you have...

The ICEM CFD Prism algorithm can not move hexa's out of the way as it inflates the prisms. Therefore, you need to make sure that you don't convert tetra to hexa before prism inflation.

With ICEM CFD, there are always other ways...

1) You could try a Hexa (blocking tab) mesh. This would be really easy if you really wanted to do a sphere in a box... What is your real application? Aircraft shapes, wings, etc. are also pretty easy to do with Hexa blocking. It gives...
