This is a general problem with numeric calculations - if your matrix has a big spread of values - some are very big while some are very small, you will eventually get roundoff errors which prevent or hurt convergence. In this case, it might be useful to manipulate the convergence parameters (In...
Another option.
Extract the face of the duct (cross section)
then extract an isoparam from the duct, and use it as a guide for the sweep.
thats assuming you have GSD module.

"behind-the-scene" means all the operations you don't really interact with.
In cad it could be automatic feature recognicion, in FEM it's the analysis part (not the modeling), and the same goes to CFD and rendering.
all interactive operations are NOT multi threaded. The iea os...
In general, only "behind the scenes" operations are multi-processor enabled.
The same goes to any 3D package, like maya, XSI and 3dmax, where the rendering uses as many cpu's you have, but the workflow uses only one, with few exceptions.
the possible advantage in multi-cpu system in this case...
What is your analysis purpose? and experience?
catia has not real good solid meshing - considering tet mesh not a really good one.
for hex meshing you need other software - ansys, msc, and the rest.
loads are applied as specified in the catia help system. again, it all depends on your...
this is more of a CAD question, but I would make an arc, and then place a coord system in the base of it, and revolve the arc the required degrees :)
this way I think you'll get ISO-Meshable surface.
you have the ability to model while using the automatic constraints - parallel, coincidant, collinear and more.. just make sur the correct button is pressed when you do the profile (don't remember the button name).
worse thing I had was a crash of catia - some really bad feature recognition...
but to get BSOD? (blue screen of death) thats quite rare now, especially if you run it on winxp SP1+
