    Assembly Symmetry - Threads aren't mirrored

    Assuming the symmetry is obvious, then specifying (xN) where N is the number of holes with the same thread specs, would be enough.

    Simulating microstructures in a reasonable time frame

    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...

    Need to get centre curve from dumb solid?

    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. jake

    more than 1 processor for CATIA

    "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...

    Contour and structures

    in general, you can do it even in excel, assuming you have velocity as a function of coordinate.

    more than 1 processor for CATIA

    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...

    good to know. if that fluent 1.10 for catia?

    Assembly analysis and the meshing methods

    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...

    segment of a sphere

    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.

    How can i mesh a solid?????

    for really good meshing, you need to use an addon..

    CATIA V5 Sketch - automatic constrains

    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).

    Blue Screen & Catia

    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+
