 January 13, 2003, 08:18 parametrization #1 Stex Guest   Posts: n/a I have to optimize a wing profile. How can I set up the variables and functions (like sin cos tang) ? Anyone have an example of session?

 January 13, 2003, 09:52 Re: parametrization #2 Roman Guest   Posts: n/a Hi Stex! You can use the tool -> expression editor to define you own function or to use standard function (sin,cos, ... ). Or you write it in CEL in your CCL-definition file (Use tools -> OS Command Line and a text editor)

 January 13, 2003, 13:40 Re: parametrization #3 Holidays Guest   Posts: n/a Hi Stex, I think you want to set this up in PCL (PatranCommandLanguage) so that you can adjust your geometry? Am I right? In this case give a look at thye Patran/Nastran language (it is briefly described in CFX course notes) and use the Perl provided within CFX-5 to run loops of "optimisation" based on the results you post-process in Post that feed algorithms that will drive the writing-up of adjusted parameters in the session file for Build-5 (all in Perl).

 January 16, 2003, 10:41 Re: parametrization #5 Roman Guest   Posts: n/a Hi! What exactly do you mean? Do you want to create a geometry or a simulation variable (like velocity or concentration). I thought about the second one. Bye!

 January 17, 2003, 08:41 Re: parametrization #6 Stex Guest   Posts: n/a I want to create a Geometry, Roman, beginnig from the creation of parametrized points!!

 January 17, 2003, 08:51 Re: parametrization #7 Roman Guest   Posts: n/a Hi Stex! Sorry, but I create my geometry only in CFX build (common methode) and never have used the parametrisation. So I don't have experience with this too. I thing Holidays can help you to do this. Bye, Roman
