airfoil coordinates / vertex data

husker · November 17, 2011, 13:36

Hi all,

Is it possible to import coordinate data for using in skecther in CCM+?
Or how do you do it when you need to skecth from many points?

Regards

Currently importing vertex coordinates doesn't work, but some people already complained about that. I don't know whether the guys at CD-adapco will implement it soon, but at least they know about this issue.
I haven't tried it, but what about writing a macro which puts the points for your spline and connects them? The macro could read the coordinates from a csv file.

Hi abdul,

As you suggest, I had to write a macro to do that.

Notes:
The macro reads and imports points onto a specific plane.
So the vertex data has to be cartesian 2D.
However I don't know if it is possible to import 3D vertex data.

Regards

Reading 3D points depends on your data. What you could do is to create several planes and a spline on each of this planes. Then you could create an element (Not sure if it's a loft or a sweep, I usually mix it up

) using all of this splines an changing it's shape while travelling along its length.

What you can't do is to import arbitrary points on the surface and create a body from this since the 3D CAD-modeller is just a simple tool compared to a dedicated CAD program.

Thank you. Creating dedicated planes for each vertex is a good idea to import 3D data.
