New WIP Release (1.4 2017-03-31)

By on Mar 31, 2017 in Uncategorized |

We’re pleased to announce the release of a new Work-in-Progress (WIP) version of Orca3D (1.4 WIP 2017-03-31). This WIP will expire on October 4th, 2017. Please note that this release no longer supports Rhinoceros version 4. This and future Orca3D WIP releases require Rhinoceros version 5. Enhanced Features: In the Orca3D Simerics Marine Simulation interface: Implemented the ability to create self-propelled Simerics simulations by defining one or more propulsors in the model. Implemented the ability to adjust the surface mesh created by the Rhino mesher for export to Simerics as well as the ability to display mesh faces whose area or aspect ratio are beyond a user-specified value. Implemented the ability to accept closed Rhino mesh geometry as input to the marine simulation command. In addition to allowing users to create the marine simulation from native mesh geometry, this also allows users to create a mesh from a closed polysurface and perform any desired pre-processing on the mesh. Added the ability to select more than one closed body for the marine simulation. This allows users modeling catamarans to avoid having to model the connecting structure as long as it has no significant effect on the simulation. Added the ability to control the mesh density and size of the domain created in the Simerics analysis. Also added logic to estimate the required time step and simulation length. Implemented persistence of all input to the marine simulation Bug Fixes: In the Orca3D Simerics Marine Simulation interface: Fixed several unit-related bugs when operating in non-SI unit systems Fixed bugs related to model orientations other than the default x-longitudinal, z-vertical orientation Fixed a bug in which the Rhino surface mesh of a closed polysurface was not necessarily a closed mesh.   As a WIP, there will certainly be feature additions, changes, or removals before the final release, but this is your chance to give us feedback and suggestions. A few important notes to be aware of: This version of the 1.4 WIP will function only with Rhino 5, and not with Rhino 4. You should have Service Release 12 or later. Only one version of Orca3D may be installed at a time. Therefore, you must uninstall Orca3D from your computer before installing this...

New WIP Release (1.4 2016-10-28)

By on Oct 27, 2016 in Uncategorized |

We’re pleased to announce the release of a new Work-in-Progress (WIP) version of Orca3D (1.4 WIP 2016-10-28). This WIP will expire on April 1st, 2017. Please note that this release no longer supports Rhinoceros version 4. This and future Orca3D WIP releases require Rhinoceros version 5. New Features: A new command was developed to interface Orca3D with the Simerics Multi-Physics (SimericsMP) Computational Fluid Dynamics (CFD) analysis tool. The command, OrcaSimericsAnalysis, has the ability to use the Design Condition or any user defined loading condition to compute the model’s hydrostatics and world placement. The hull model must be a closed, solid body, and the user must attribute the Faces of the model as belonging to the Deck, Hull, or Transom. The command exports the model as custom STL files, and then creates the SimericsMP simulation files based on a Simerics Template and the analysis type (displacement or planing) for each speed to be analyzed. Finally, the command allows the user to launch SimericsMP with a selected simulation file. SimericsMP will open the simulation file and will automatically generate surface meshes and volume grids that are suitable for the requested simulation. Enhanced Features: Split the developable hull assistant extension curve into unique forward and aft controls. Bug Fixes: Fixed multiple bugs causing instability in the developable hull assistant. Improved handling of non-developable input data. As a WIP, there will certainly be feature additions, changes, or removals before the final release, but this is your chance to give us feedback and suggestions. A few important notes to be aware of: This version of the 1.4 WIP will function only with Rhino 5, and not with Rhino 4. You should have Service Release 10 or later. Only one version of Orca3D may be installed at a time. Therefore, you must uninstall Orca3D from your computer before installing this WIP. No change to your License is required. The new version of Orca3D will find your existing License. Portions of the Help file may not be entirely up to date. This WIP will expire on March 1st, 2017. Either a new version of Orca3D will be released before then, or a new WIP will be released. If you have questions as you install and use...

Design Hydrostatics: What is the Design Condition for?

By on Oct 11, 2016 in Uncategorized |

Simply put, Design Hydrostatics is a subset of the complete Hydrostatics & Stability calculation. The idea is to make it possible to compute hydrostatics with a single button click. Without Design Hydrostatics, the usual steps to compute hydrostatics are: 1. Select the surface(s) and/or mesh(es) to be included in the calculations 2. Start the Orca3D Hydrostatics & Stability command (Orca3D->Stability->Compute Hydrostatics & Stability) 3. Define the flotation condition (weight/cg or flotation plane, etc.) 4. Set the options (Mirror about Centerplane, etc.) 5. Click Calculate While this gives you a lot of flexibility and options, many times while you’re shaping the hull you just want the hydrostatics at a particular flotation plane or weight/cg, and you don’t want to have go through each of these steps every time. The Design Hydrostatics allows you to define a special condition (the “Design Condition”) once, and then while you’re working with the hull you only need to click the Compute Design Hydrostatics icon to get hydrostatics computed in that condition. To define the Design Condition, go to Orca3D->Stability->Define Design Condition. Select the surface(s) and/or mesh(es) to be included, define the flotation plane, and check any options (such as Mirror about Centerplane). The Design Condition is now defined, and to get hydrostatics quickly just click on the Compute Design Hydrostatics button. Keep in mind that if you delete one of the surfaces or meshes that were included in your Design Condition, you will need to redefine the Design Condition. Also, the surfaces or meshes that you select for a standard Hydrostatics & Stability calculation will now become the surfaces and meshes for the Design Condition, unless you redefine...

New 61m Cat Design from Sedlmayer Associates Released

By on Sep 2, 2016 in Uncategorized |

A spectacular new 61 meter luxury catamaran design has been completed by Sedlmayer Associates, naval architects based in Southport, Queensland, Australia. Rhino and Orca3D were instrumental in the design process. Albert Sedlmayer describes the design and the design process: SEDLMAYER ASSOCIATES PTY LTD developed SPECTRUM 61 from Hand-sketched pencil ideas straight to Rhin03D, without a 2D draughting stage in between. It has been much more efficient and more accurate this way, with no nasty surprises later on. Very early on SPECTRUM 61 established her unique character and made it quite clear which features she wanted and which she rejected, so we developed a family of structural details to suit, to avoid the stress concentrations usually associated with these sharp features. Below the chine/spray-rail we used Orca3D’s dynamic lines function to quickly establish fairness and optimal transition of water-flow between strakes. Above the waterline nearly all predominant surfaces are segments of pure geometric sphere, cylinder and flat primitives, as her character demanded. The hull topsides, chine to sheer, are derived from a spherical segment comprising only three master stations over her 61 metres with three vertices each, and only the bow vertices pulled into the hull centreline. This assures a planar sheer. The resulting maindeck surface is then a saddle-shape with minimal vertices and arc sections. Orca3D was used extensively right from the first hull sketch, to monitor and optimise displacement, hull coefficients and areas curves. We used Orca3D’s Holtrop analysis to calculate resistance and determine engine power and optimum speed range. We have found excellent correlation between Orca3D’s Holtrop results, tank testing and deployment feedback of our ships in service, and are very confident in these results. We assign weights to fitout and general arrangement components from early on using Orca3D weight and cost features. These are refined and updated as the design progresses. We assign weights to all structure components as they are developed in Rhino, and thereby keep extremely accurate running weight and CG control. Temporary PC weights are assigned to parts still to be determined, and updated during the design process. A. Sedlmayer Sedlmayer Associates Pty. Ltd....

Creating a Planar Sheerline

By on Aug 23, 2016 in Uncategorized |

A planar sheerline will never show any inflections, no matter the view. It will always be completely concave, convex, or flat, no matter your vantage point. Many believe that this is the mark of an “elegant” sheerline. In this new video from NDAR, you will see how to place the control points along the sheer in a plane, resulting in a planar...
