Radial Inflow Turbine - Topology Error (Turbogrid)
I have a problem when trying to create the topology with the ATM Method in Turbogrid. It works perfectly fine, if I exclude the Splitterblades, but fails to find the right topology when included them.
I get always the same error message:
“An error was thrown generating the span geometry for MID. This probably means the selected topology is not appropriate. Details are given below: U value outside of its bounds. Value = -0.00343816”
The value changes slightly, when modifying the radii for the round off of the blades, or when increasing the number of points along the blade or the LE and TE but never vanishes.
I had constructed my radial inflow turbine with the Ansys DesignModeler. I tried even with the BladeGenerator a similar blade and export it to the Turbogrid but with little more success.
The blades are defined as followed:
*Number of Blades: 10 (+10 Splitter Blades)
*Trailing and Leading edge of both Main and Splitterblades are rounded off
I will include the geometry file, so anyone can try to resolve the stated problem.
I hope anyone has an idea, as i would like to include turbogrid instead of ICEM for the creation of the stator and rotor mesh.
