How to find rake of a B series propeller
Mr. Heinrich von Zadow replied to ALTHAF K.B's topic in General Modeling
It's part of the documentation that comes with CAESES. You can either switch to the help workspace (bottom left) and just search for it: or you create a blade and then select the Icon next to it in the object editor: Cheers, Heinrich -

Dear Althaf, in the documentation for the FGenericBlade you should find all the details, including the following figure: Best regards, Heinrich -

Dear Aina, I am happy to take a look but would need the project file and/or the exported IGES you mentioned. From the screenshot it looks as if your geometry is not fully watertight -- that might be a starting point for investigation. Furthermore, the displacement calculation is based on the triangulation settings -- the coarser, the larger the error. But typically the deviations here are not as large as you experienced them. Finally, if you calculate displacement at a certain draft, heel and trim, the order of transformations and the origin you choose may drastically impact the result. I don't know about Numeca, but in CAESES we transform in the order heel, trim, draft and use [0,0,0] as default origin. You can also specify otherwise by using the .getDisplacementOrigin() command. Kind regards, Heinrich

NUMECA FINE MARINE CONNECTION
Mr. Heinrich von Zadow replied to Solehah's topic in Software Connections
Dear Aina, typically the absolute path to your FineMarine installation followed by a space (" ") and the path to the *.sim file should work. Just check it manually in a terminal window. Best regards, Heinrich- 15 replies

NUMECA FINE MARINE CONNECTION
Mr. Heinrich von Zadow replied to Solehah's topic in Software Connections
Dear Solehah, thanks for preparing the file. Here's a few comments: 1. I can see that you have a number of individual Trimesh Parts. None of them has a color. Typically what you would want is a watertight geometry of the domain with the individual patches colored (the color names will be exported as the names of your boundary conditions). I recommend you color the individual parts and join them together in a single Trimesh like this: 2. Make sure to reference to the exported geometry in your sim scripts (maybe I just overlookerd it, but I could not find the file names you used for the exports in there. Lines 8-9 in your existingShip.iec file don't look good. 3. Your Connector runs the local Application FineMarine without any additional arguments. I imagine that you either need to specify the sim file as argument or, alternatively come up with a batch file that takes care of running things. 4. If you want to have parameters for certain inputs you will need to assign them to your configuration (i.e. drag & drop): I'll leave it at that for now. If you still run into trouble, I highly recommend you follow through a few tutorials on the subject. The procedure is always very similar. Best regards, Heinrich- 15 replies

NUMECA FINE MARINE CONNECTION
Mr. Heinrich von Zadow replied to Solehah's topic in Software Connections
Dear Solehah, since this is a forum, I'd would like to ask if you can provide a (possibly simplified) version of your project that you are willing to share with other users? This way we can create a knowledgebase that allows the entire CAESES community to benefit. Best regards, Heinrich- 15 replies

NUMECA FINE MARINE CONNECTION
Mr. Heinrich von Zadow replied to Solehah's topic in Software Connections
Dear Solehah, you can refer to the provided tutorials on software connection. The basic principles are always very similar. After you have tested things manually you should know what geometry is needed and in which format. My guess is a colored STL of half the domain with the ship substracted from the domain at roughly the right floating condition. Extra care needs to be take to account for triangular patches as I mentioned in my first post. If you want CAESES to read in pictures generated from Numeca (or any other tool in your chain), PNG works fine. You will want to run Numeca in batch mode to avoid the GUI showing up.

NUMECA FINE MARINE CONNECTION
Mr. Heinrich von Zadow replied to Solehah's topic in Software Connections
Dear Solehah, at least I can't see anything that's obviously wrong from the screen shots. If you have an STL I would recommend that you start by setting everything up in Numeca (completely independent from CAESES). Once things are meshing and running/converging the way you want them to, you can go back to testing the CAESES integration. This way it's easier to know where to trouble shoot...

NUMECA FINE MARINE CONNECTION
Mr. Heinrich von Zadow replied to Solehah's topic in Software Connections
Dear Solehah, A Mesh Engine will only allow you to generate surfaces meshes as you would need them for potential flow simulations i.e. for wave making resistance. To run ranse CFD in Fine/Marine you would need to use their HEXPRESS grid generator and supply the flow domain as an STL. Best regards Heinrich- 15 replies
