  1. 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.
  2. Hi everyone, I coupled CAESES and Starccm+. I'm trying a cycle out. As you can see on screenshot, it says n/a for "eval_coeff"; but when i click on created design, i can see the value on the left side. It does not count in the "eval_coeff" value when making evaluation. How can I overcome this problem? Any idea?
  3. Hello, I am really new to CAESES and I tried the s-duct tutorial, followed all steps but I am getting an message: External process start failure [Starting process C:/Users/HP/Desktop/skola/DP/sduct/sduct/manual_results/baseline/Runner//Allrun failed: Process failed to start:] Currently using OpenFOAM v1912 installed on Ubuntu 18.04 for Windows 10, Allrun and stdouterroroutput files are attached. I will really appreciate any help! stdouterroroutput.redirect Allrun
  4. Hello Everyone, I've tried my hands on CAESES+CFX integration and i think its worth sharing for those interested in using Ansys CFX. This was done with ICEMCFD as the mesh tool (rpl script file). The key files needed from CFX are the *.pre and *.cse. Ive attached a project file that shows how the integration was done. To run in batch mode, you'll need to call cfx5pre, cfx5solve and cfx5post executable( please check attachment). I've also attached a process workflow to describe how the integration works. To post process in CAESES, you can check the tutorials for more details. (C:\Program Files (x86)\FRIENDSHIP-SYSTEMS\CAESES\tutorials\01_getting_started\postprocessing.pdf). Cheers, Richard Project1_elbow.fdbc
  5. Hello everyone. In the attached file, there are an sample hull, feature definition for connection to Maxsurf to get Large Angle Stability results. When I click to run button, console says that "Initializing BentleyStability - please be patient ... ... initializing BentleyStability failed - aborting" Anyone knows how to fix this? Thank you in advance... shiphull.fdbc
  6. Hello to everyone. Is there anyone who's made integration between Caeses and Maxsurf Stability/ Maxsurf Resistance before? If any, can you please share it to me to learn how to make it? Regards, Hasan.
  7. Hello friends,   Currently, I can use CAESES to read the points of a curve (function (x,y)) and then export into csv file. Is it possible to further calculate the slope or derivative of this function using CAESES programming and then export a csv file? Or any other way to do this without programming? Thank you guys.    
  8. Hi, Please find attached a feature definition that you can use for exporting blades into the geomturbo file format. Note that this export will be included in one of the next CAESES releases (menu > feature definitions > tools). If you need it right now: Just put the definition into the feature user directory (e.g. C:\Users\name\AppData\Roaming\friendship\features) to directly access it through the menu in CAESES. Cheers Joerg PS: Check also this related post for importing geomturbo files, as well as our company blog post about this topic. GeomTurboExport.fdf
  9. Hi all, I'm doing an optimisation on an axisymmetric body. I have manually generated the coordinates of the profile by variating the parameters and put them in individual CSV files(got 200 of them!!!). I want CAESES to generate the geometry for each CSV file and run the analysis in Star CCM+ automatically and save the results. I want to know if this is possible or not, if yes then please please guide me :)
  10. Ladies and Gentlemen I have a short introduction about the evaluation project of propeller open water test using CAESES + STARCCM+. You can find the whole contents at the link below. GO :D
  11. Hi All, Recently I wanted to investigate the use of OpenFOAM for CFD calculations for a model built in CAESES and perform an optimization at a later stage. Although the OpenFOAM is a C++ library meant to be run in Linux systems, I wanted to test the configuration on my Windows pc and I found this compiled OpenFOAM 2.3 version available. After installing the software as instructed I had to change a little bit the configuration of the software connector in CAESES. Basically, I called the mintty.exe terminal application and run a modified version of the Allrun.sh shell script, as demonstrated at the ahmed body sample. You can find attached a picture of the LocalApplication and its arguments, the modified shell script Allrun.sh and the modified project file of the Ahmed Body sample provided with CAESES installation. Please notice that I have configured the OpenFOAM calculation to run on a single processor and deactivated any parallel computing, because of my restricted resources, but you could easily restore that back. I had also to change some points in the RunFunctions file located in /opt/OpenFOAM/OpenFOAM-2.3.x/bin/tools and you can find attached this new file too. If you are interested in learning how to manipulate OpenFOAM or try some simple simulations on your windows machine, you can give it a try. Cheers, Ilias. ahmedbody.fdbc Allrun.zip
