Ansys TurboGrid

*.tse or *.inf, *.curve; *.cfturbo-ansys

I

S

V

MC

2 alternative formats are available:

a) Session file *.tse (not available within Ansys Workbench)

4 files are created: a session file <filename>.tse and
3 geometry files <filename>_hub.curve, <filename>_shroud.curve, <filename>_profile.curve.

Load the session file <filename>.tse under Session | Play Session.

b) Initialization file *.inf

4 files are created: a initialization file <filename>.inf and
3 geometry files <filename>_hub.curve, <filename>_shroud.curve, <filename>_profile.curve.

Load the initialization file <filename>.inf under File | Load TurboGrid Init File.

Alternatively you can open the curve files (<filename>_hub.curve, <filename>_shroud.curve, <filename>_profile.curve) manually under File | Load Profile Points. Beside the selection of the *.curve files one has to specify the number of blades, define the z axis as rotational axis, select the cartesian coordinate system and the length unit specified in CFturbo for export.

The cfturbo-ansys file contains project and fluid data.

- geometry data file <filename>.geo
- aerodynamic data file <filename>.aer
- correlation data file <filename>.cor

Run compiled executable version of the Vista TF code. Exported files need to be in the same folder than the executable file.

Possible warnings

Problem

Possible solutions

Flow inlet does not match previous outlet.

 Impeller - Impeller

 Impeller - Stator

 Impeller - Volute

 Stator  - Impeller

If possible, activate the RSI connection in CFD setup of the impeller.

 Stator - Stator

 Stator - Volute

Inlet geometry was defined in such a way that it does not match the inlet of the previous component. See geometric coupling for more details.

Flow outlet does not match next inlet.

 Stator - Stator

 Stator - Volute

Outlet geometry was defined in such a way that it does not match the outlet of the next component. See geometric coupling for more details.
