[Deus Ex Machina]

Hi all,nI am working with centrifugal compressors with CFX, Fluent, typical Turbogrid, BladeGen, etc.nI already finished the whole machine except the volute and I don't know where to start.nIn general, what is the best way to do this today?nThanks in advance.n

You can check SpaceClaim. nPlease see help manual for more details about these commands. nnRegards,nKeyurnGuidelines for Posting on Ansys Learning ForumnHow to access ANSYS help linksnn

Excuse me sir, I don't understand your answer. Obviously we can always do all the geometry from scratch using SpaceClaim, but it takes a lot of time and effort.nFor this reason ANSYS creates specific modules to simplify industrial problems.nFor example, Vista CPD (Pump Design) has this module, but CCD (Vista Centrifugal Compressor Design) does not have volute generation. This is a bit strange.nI have done both the impeller and diffuser (BladeGen, TurboGrid and CFX) and now how do I finish it all?nThanks for your answer.n

If you have all the bits separately export the geometry & read it all into either DesignModeler or SpaceClaim. You asked how to generate the volute, so pointing you at the geometry tools is a valid answer. n

Dear Rob,nIt can always be done from scratch with SpaceClaim, I know. I can also make the impeller with SpaceClaim or DesignModeler, but as a consequence of the complexity, time and effort, ANSYS provides us with individual modules to make these parts (BladeGen for example).nI ask about this fact. Obviously all CAD can be done from scratch with SpaceClaim or Design Modeler: impellers, diffusers, etc. We all know.nFurthermore, there are other programs (different from ANSYS) with which compressor volutes can be designed in the same way as BladeModeler or Vista CPD, so it is strange that ANSYS does not provide this component.nThat is why I ask how ANSYS solves the design of centrifugal compressor volutes. I hope these words clarify my question.nI hope I am not read unfriendlynThank you very much.n

Dear Rob,nI respectfully asked him how I can design within ANSYS a complex turbomachinery component: a volute.nIt can always be done from scratch with SpaceClaim, I know.

I tend to assume most posts aren't intended to offend, working with non-native English speakers helps with that. We also get soft skills training inflicted on us as irregular intervals. nCompressor & turbine design is a very complex process, and whilst some of our tools help with the process we don't (can't) cover all of it. Volutes and some blades/discs are still hand carved and scanned for example, others are drawn using profiles that we skin/loft afterwards, additionally other (third party) design tools exist, and as we're CAD agnostic we just read those in.
