Printing a 3D model from an Iso-surface from CFView.

Delfim Sa

I have this iso-surface from CFView:

I want to 3D print it. Has anyone in the community ever done something similar? Is it possible to export this as a surface or a solid from CFView?

Any help will be appreciated. I have already tried using Export Active Surface, but that extracts a list of points that are too complex for other programs like SolidWorks, Meshlab, or Cloudcompare to work with.

Any ideas?

Thank you very much.

Regards,

Delfim Sá

    Within the CFView toolbar, specifically in the geometry tab, there are two available options: "Export Active Surface" and "Export CGNS Active Surfaces" . Several tools are available for converting CGNS to STL format.

    Thank you for your reply. I found it difficult to do that conversion since the surfaces provided from the iso-surface tool are not closed so this cause a lot of errors. The way I have done it is:

    1º - get the surface as a point cloud

    2º - use cloudcompare to slice the point cloud in smaller block. This block should have only have either the SS or PS of the blade.

    3º - run a simple python scrip to only have one layer of points per block. In this way he get the figure of the artifact without having to deal with the normals error in the next step

    4º - use cloudcompare to calculate the normals of the each block. Make sure they are all facing the outside of the surface. Merge all blocks in one mesh.

    5º - Use cloudcompare to poisson tool to make the surface

    6º - Use meshlab to close any hole or repair the mesh.

    7º - print

    This is how i did it. But I did see advice to use ANSYS ICEM CFD. Do you know a way to make this easier?

    Based on my understanding, you require solely the surface data of the blade for the purpose of 3D printing. If you only require the blade surface data, it may readily extracted. There is no requirement for an Iso_Surfaces in this situation. To obtain the blade coordinates, you can divide the blade into multiple sections and cut from hub to the tip. The utilization of turbomachinery mode is applicable for this extraction process.
