A turbo surface is a surface that exists only within the boundaries of the geometry and is defined using variables specific to rotating machinery. To create a new turbo surface, select Insert > User Defined > Turbo Surface from the main menu.
Ansys TurboGrid creates a turbo surface using a defined variable and its value.
Set the domain to either All Domains or
DOMAIN:Passage. Select a variable and set a value
to define the location of the turbo surface. (The variable is
"K" by default, which is the mesh plane index that varies from
hub to shroud for the H-Grid and J-Grid topologies.) You may enter the value
directly, or, for the "K" variable, use the up/down arrows,
or, for any other variable, click in the Value box,
then click Enter Expression
(to the right of the Value box) to
enter an expression for the value, or use the slider.
