  2. Dear Heinrich, I have sent the file using personal massage. Hope you can give some feedback on the setting. Thank you
  3. Last week
  4. Earlier
  5. 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
  6. Hi, I am currently doing my final year project which my boat is Monotricat vessel. Here I attach a picture for my question. As you can see the displacement is a volume in the picture, so the volume that i got in CAESES is 73m^3, but I import this file igs from Numeca and the volume is 75m^3. Do you know what is cause of the error between Numeca and CAESES volume about? I try my best to find the solution but could not found out. I hope to hear the solution from your team. Thank you in advance
  7. Hi Hedi, I installed CAESES 4.4 32-bit and it is working. I will use this version instead. Thank you for your help, Antoine
  8. Hi Hedi, Thank you for your reply. I was always able to select the parts in the 3D viewer when I drag the mouse cursor around but I cannot see them. I made sure that all individual parts are set to "visible" but nothing changes. Is it a problem with my laptop graphical card/settings? Do I need to set up the 3D viewer at the beginning? Regards, Antoine
  9. 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
  10. Dear Heinrich, Sorry for disturb you. I have some question for number 3 which is "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." For the batch file, do you have any example or explanation what i need to put in the content/script ? Thank you in advance
  11. Dear Lixing, The questions you are asking are explained in detail in the type documentation -- just click the icon left of the name of your blade. Also note, that you can choose between different options for the representation of skew and pitch: Best regards, Heinrich
  12. Hi friends! I am trying to modeling a marine propeller in caeses, in the process, i am very confused by the meaning( chord,thickness,camber,skew and rake ) of propeller in caeses; According to my understanding 1 chord is a dimensionless parameter that can be defined as chord length/radius? 2 thickness,camber can be regarded as maxthickness/chordlength and camber/chordlength? 3 But what is the defination of skew and rake, skew/radius or skew/chordlength??? can anybody help me? Best regards
  13. 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
  14. Dear Heinrich, Sorry for the late reply. Here I attached the file. Thank you. Hull Variation test1.cdbc
  15. Hi Mr. Claus,

    Im doing my research about optimisation modelling toward reducing ship resistance.

    So here i want to connect CAESES with Numeca and i want Numeca run as a background of the simulation to get the resistance, but when i want to run to get the result value, Numeca interference keep pop out which it tell to run in Numeca. Here i attach the picture, in the picture i take the result from Numeca. Can you give me some advice Mr Claus, if my setting is right or not. 

    Thank you in advance


  16. What kind of geometry to you use? Trimesh or BRep? Can you upload your model, please?
  17. 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
  18. Dear Heinrich, I have sent the file using personal massage. Hope you can give some feedback on the setting. Thank you.
  19. You can find the function in the Help Workspace, see screenshot below.
  20. Hello folks. I’m new to CAESES and I have a little question. I wanna get the value of the arcus tangens function, so which command would work? Thank you for your time in reading and responding to my question. Hope to learn lots!
  21. Dear Latoya, thanks a lot for the flowers! Cheers, Heinrich
  22. Hello everyone. After a while using CAESES, I must say developers have done a great job to offer us such a helpful tool. I’m writing this post to show my appreciation and gratitude towards you all, hopefully this can encourage you to do it better in the future.
  23. Thans for sharing this, it's helpful and useful! There are lot of free cad software exist such as Fusion 360, FreeCAD, Onshape, OpenSCAD, BlocksCAD, TinkerCAD, QCAD, LibreCAD.etc Here's a good article about cad and technical drawing software: https://www.xp-pen.com/forum-6119.html
  24. 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. Best regards, Heinrich
  25. I have done running in NUMECA. Meshing and so on. Can you give me some advice on how to connect with CAESES. Such as what file should the geometry be imported? What kind of file should be imported; does it need some programming from NUMECA for the input file. For result file, does it need PNG file from CFView? I had already tried running CAESES after input the files, but the NUMECA interface pop-out. It does not run in the background and did not get the desired output which is resistance. Based on the video on Youtube, shape optimization using Caeses and STAR-SSM+, the star-ccm seems to be running in the background and its interface does not pop-out.
  26. Hi, Attached you can see there are three bodies. Body 1 is a wing, Body 2 is a fuselage, and Body 3 is a side body kinda thing. All these three bodies are union-ed using the boolean operation. When I activate the filleting it doesn't show anything or if I change the radius/distance it jumps out with segmentation fault. What is the best practice to put fillet on the connection edge between these three bodies. p.s. since these three Brep bodies are parameterized their size is changing. Cheers, Pay.
  27. 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... Cheers, Heinrich
  28. Hi Pay, this is hard to say, without seeing the model. In general we always recommend to model in millimeter, because this will increase numerical accuracy, which also could lead to more stable fillets. Best regards Carsten
