Turbogrid Meshing
 

How can I preserve curves of design modeler into turbogrid meshing?


I have extracted curves or lines from CAD of compressor impeller blade and then I created 'Flowpath' in bladeeditor of design modeler. Then I use 'CAD Import' feature and exported script. Then I run script in another designmodeler. This is how I have now sector model of blade, which includes blade, splitter, shroud , Ported Shroud and hub.
This shroud has sharp curves at inlets and I want to preserved that shape as I am going to create an interface with ported shroud.

I found a possible solution, in the design modeler, blade editor model settings, I enabled advanced features.

This open up a new option in 'flow path' interpolation mesh size, which I put a value of 2000 * number of blade row. and I am able to preserve the flow path curves.

But still when importing into turbogrid because the curve representation is 'Bspline' it was not preserving the curve. I used 'Piece-wise Linear' and together with 'Use True Surface For Projections = true' then it preserved the curve. But it is somehow not allowing to generate mesh at shroud tip.
