Centrifugal Pump Design with Ansys TurboSystem - Part 2
Introduction
Welcome back! In the first part of our video series, we designed a centrifugal pump. We focused on two main components: the impeller and the volute, using Vista CPD and BladeGen tools. In this video, we will concentrate on the mesh generation for these two components.
Mesh Generation for the Blade
We begin by transferring data to TurboGrid. Before opening TurboGrid, we need to adjust some properties:
- We do not want an outlet domain, as we aim to have a gap between the two components, with the volute acting as our outlet domain.
After unchecking the outlet domain option, we double-click the button to open a new TurboGrid window, which automatically uploads our blade model. TurboGrid is an excellent automated hex mesh tool, particularly designed for turbomachinery applications.
Steps in TurboGrid
- Inspect the single sector blade model displayed in TurboGrid.
- Navigate to the topology settings.
- Unsuspend the topology to build the mesh.
- Wait for the mesh generation, which may take a minute.
- Inspect the generated mesh for quality.
The generated mesh features high-quality hexes and a nice boundary layer wrapping around the blade. The mesh analysis does not show any warnings or errors, assuring us of a quality mesh. We can then proceed to the next step by closing this window.
Mesh Generation for the Volute
Next, we need to mesh the volute part:
- Create a new volute, which automatically opens two programs:
- Design Modeler: A CAD tool optimized for turbomachinery flows.
- Workbench Mesher: Automatically updates geometry and generates the mesh.
The geometry is built cleanly, indicated by a green check mark. The Workbench Mesher uses automated settings for a volute mesh, ensuring a streamlined process.
Conclusion
This concludes our mesh generation process for the centrifugal pump design. We have successfully created high-quality meshes for both the blade and volute components using Ansys TurboSystem tools.

Hello, welcome back. In the first part of our video, we made a centrifugal pump design. In two parts, we designed our impeller and our volute using Vista CPD and blade gen tools. And in this video, we're going to focus on mesh generation of these two components. So let's first start with our blade.
What we want to do is transfer data to TurboGrid. And before I open TurboGrid, I want to look at the properties. So let's move it here. I do not want an outlet domain because I want to have a little bit of a gap between the two components. So we're going to have the volute act as our outlet domain.
I'm going to uncheck that, double click on the button, and this is going to spawn a new TurboGrid window, and it's going to automatically upload our blade. TurboGrid is an excellent automated hex mesh tool that is particularly designed for turbo machinery applications.
Here, we can see the single sector blade model. This tool is fairly easy to use. A lot of times, without much user input, you can get a good quality hex mesh. After a bit of inspection, I'm going to go to topology set, unsuspend, and build the mesh.
It's generating high-quality hexes and a nice boundary layer wrapping around the blade. The mesh analysis does not give any warnings or errors. We can then move on to the next step by closing this window. We also need to do meshing on the volute part. So we're going to go to create new volute.
This is automatically going to open two programs: Design Modeler, which is a very nice CAD tool optimized for turbo machining flows, and the Workbench Mesher.
It will automatically go through the geometry update as defined from Vista and then automatically generate the mesh for us without us having to provide any inputs. Currently, it's building the geometry and meshing in the background using Workbench Meshing with automated settings for a volute mesh.
