    NACA66 (MOD)

    Ok. i do this which tou tell me. I run the script. It worked and the points of NACA showed. Now, what am i do? How i make the spline with this points?

    NACA66 (MOD)

    Yes... Initially, I thing to do spline with a few point which i have, but can not do this. With Autocad 2008, do you know how became this procedure? 1. how input the points? 2.How make a spline with these points? Thanks very much for information!!!

    NACA66 (MOD)

    I want simulate this NACA with CFDs. And i must have a lot of point because the Gambit(if you know: program for decrizitation), put the points and connect them with lines. Thus , in reality, i have a polygon and no curbe and then i have problem at finite volume near the wall. Can you sent me...

    NACA66 (MOD)

    Maybe. But The numbers of this NACA (66-412) what mean? With other words, this NACA has at 45% max thick? Where look it? Also i want a lot of points. at least, 500 points for any section and more densely at leading edge.

    NACA66 (MOD)

    Hi. I will work with a NACA 66 (MOD) in an exersise and i want all points or function which describe this NACA. This NACA has characteristics: max camber 2% at 50% and max thick 12% at 45%. I search everywhere but i don't found nothing. Can anyone help me? Basic i found some Java programs at...

    Modeling flews

    i try to solute other geometries with some gibbocities but the end is occured the same state. ? don' t know what happen here but it may need more boundary contitions for solution. i Sent you this simply geometry which i make. Is 2D. I want to take the field of stress where challenge the force...

    ok. Until afternoon, i will have upload.

    Modeling flews

    i use "quade" finite elements for surfase and "hex" for solid geometry. Why dont it find a solution? Must i use a special finete element?

    Modeling flews

    Hi! I try to construct a model of flaw at Patran. First i make a two domention (2D) model of flaw. In this i design a square shape and in this i make the flaw as thin brill. At the end i analyse this geometry with its loads but when i try to load the xdb file, the Patran send me a below message...
