CAESES is used for the parametric design of axial fans and similar turbomachinery products, mostly in the context of simulation-driven shape optimization. In particular, CAESES is used if you need robust variable geometry models for automated studies. The comprehensive CAD modeling capabilities are geared towards simulation and give fan designers full flexibility (no black box, customization possibilities). More information about turbomachinery design software can be found here. I have also attached a few animations that were generated in CAESES. The design variables of the axial fan model were varied automatically using the integrated variation methods. Note that this is a rather simple model which is also shipped with the software. It can be used as a reference design to set up custom models. The hub and shroud modeling is demonstrated, as well as the 2D-3D mapping of the cylindrical sections and some Boolean Operations to cut the blade at the tip and merge it with the hub. The fillet size can also be controlled by a parameter. If needed, you could also automatically derive the periodic flow domain for automated meshing with grid generation tools or CFD packages.
We can make a multi-segmented smooth curve from Feature Definitions -> Hull Design -> Multi Segmented Smooth Curve. The issue is I can only define '2' intermediate points in a curve. I want to join many multi-segmented curves to create a single curve. How do I do it ? I am a beginner in CAESES. I could not find it in documentation. Please help.
How to determine a spiral volute casing (turbocharger, pump) cross sectional decrease in value? I am trying to design a volute casing. Problem is, I don't know how much its cross sectional area decreases over time. For instance starting cross sectional area (0 degrees) is 100 cm^2, what will it be when it reaches 45, 90 degrees and so on? Is there any way to calculate it? I am sure that knowing starting and finishing cross sectional areas size (btw I know them) and just connecting them isn't a correct way.
