Point Cloud --> Body
 

I have data in the form of a text file with (x,y,z) coordinates of individual points that I need to make into a body of a complex shape. Ultimately the goal is to then take this body and transfer it into Gambit and mesh the object.

The only method I know about to accomplish this is Solidworks but the number of points required to get a uniform mesh is too much for the processor to handle and it eventually crashes while computing.

This is proving to be very difficult and a big road block in my project. Any help would be greatly appreciated!

Thank you

It depends on what you want to accomplish.

If you want to generate a continuous geometry out of these points, like in iges format for example, you need an optimisation process of which publications are usually not to be found in the aerodynamic corner.
(but in mathematics, rapidprototyping, lathe mechanics etc.)

Seeing that, you'll need a discrete mesh finally, you may safe yourself from this box of Pandora, by translating from discrete to discrete.

If your x,y,z nodes are not ordered/structured, you have a serious problem, the easiest solution will depend on the geometry itself and it may be worthwhile to look for the actual source that generated these x,y,z data.

If, however, your x,y,z, data are structured your "connectivity table" is trivial and can be generated, by let's say a simple loop in for example fortran or matlab.

The ascii format that I recommend for writing your result is FIDAP, most solvers can read that (of course you should check this first).
