  1. Hi together, Note that CAESES is a ship hull design software, in particular, in the context of hull form optimization with CFD (computational fluid dynamics). It mainly focuses on the underwater part. The software provides comprehensive CAD functionality for generating smooth and variable hull surfaces , a complete variant management, 2D section visualization, hydrostatic calculation, 2D drawing, Lackenby transformation, STL and CAD tools for creation of flow domains, plus integration mechanisms to plug-in simulation and other preliminary tools. Energy-saving devices and propellers can be modeled, too. Furthermore, sea-keeping tools (basically, any other external software) can also be added to the design process. Please find below more screenshots that are taken from CAESES. Cheers Joerg LAST UPDATE NOV 2018: Note that there are FREE pro editions for students and PhD students, plus special packages for start-ups, small companies and freelancers. nurbs_direct_modification.mp4
  2. Parametric models are typically built from various geometric or non-geometric entities, e.g. a projection curve depends on the curve that is going to be projected and the surface it is supposed to lay on. In most programs the user creates the desired object first (in this case the projection curve) - and is subsequently asked to supply the necessary objects (surface, curve and possible projection direction) until the configuration is complete. In CAESES/FFW missing information is indicated by a * next to the required attribute and you can set the relationship via drag and drop or typing. However, if you have selected a surface and a curve already when creating the projection curve, they will be automatically associated to the attributes. Note: Whenever the selection set fits to a creator called, the attributes will be set immediately. For every object you will find a list of available creators in the type documentation.
  3. 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.
  4. 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.
  5. 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.
