Then you just have to modify it.\r\nYou can start from the original design nested in Beltrami or load an example that comes close to your goal.\r\n\r\n## Documentation\r\n\r\nA user manual can be found [online](https://michelsabourin.scenari-community.org/Outils/Manuel_utilisateur/co/Manuel_utilisateur.html) \r\n\r\n**Note:** All the documentation has been generated in French. However, your web browser translator works very well. MS Edge seems to have the best friendly translator.\r\n\r\n![Image of Installation](Resources/Installation.png)\r\n\r\nHere is the video that presents the Beltrami workbench:\r\nhttps://youtu.be/O_abwUuA4Ec\r\n\r\n## Theory\r\n\r\nBackground on the theory behind Beltrami can be found in [this section of the manual](https://michelsabourin.scenari-community.org/SimTurbMeth/co/0__Methode_de_trace.html).\r\n\r\n## Examples\r\n\r\nSee the [Examples](https://github.com/Simturb/Beltrami/tree/main/Examples) section of this repository to find the provided examples of Beltrami in action.\r\n\r\n### Francis Turbine Blades\r\n\r\n![Image of Francis](Examples/Francis.png)\r\n\r\n### Kaplan Turbine Blades\r\n\r\n![Image of Kaplan](Examples/Kaplan.png)\r\n\r\n### Centrifugal Pump Blades\r\n\r\n![Image of pump](Examples/Pompe.png)\r\n\r\n### Turgo Turbine Blades\r\n\r\n![Image of Turgo Turbine Runner and blades](Examples/Turgo.png)\r\n\r\n### Radial Cascade Blade\r\n\r\n![Image of radial Cascade blade](Examples/CascadeRadiale.png)\r\n\r\n## Discussions/Feedback/Support\r\n\r\n* Email contact: simturbweb@gmail.com\r\n* Dedicated FreeCAD [forum thread](https://forum.freecadweb.org/viewtopic.php?f=8\u0026t=62056)\r\n* Bugs: https://github.com/Simturb/Beltrami/issues (please discuss on the forum thread beforehand)\r\n* Dedicated YouTube channel/playlist [YouTube SimTurb/Beltrami](https://www.youtube.com/playlist?list=PLBEuUSiaphy0sQsR1XlUFJ3OMMKjDw_Wx)\r\n\r\n## Warning\r\n\r\nThis Beltrami workbench is in ALPHA state along with the [Curves WB](https://github.com/tomate44/CurvesWB/) on which it is based.\r\nWith new release, reading of previous release generated file can present some bugs. To correct de situation, cold start a new file, import manually the coordinates in the Meridien sketch and do the same for variables in the Tableau_Pilote spreadsheet.\r\n\r\n\u003cdetails\u003e\r\n  \u003csummary\u003eRelease notes\u003c/summary\u003e\r\n  \r\n\t### Release 1.3.1 :\r\n\tGeneral revision of thickness law to replace tangential thickness by transversal thickness: more convenient for design. Minors bugs corrected. Examples updated accordingly.\r\n\tTransparent for user, same interface. Theory and user manual updated.\r\n\t\r\n    ### Release 1.1 :\r\n    Release 0.6.40 of CurvesWB allows to some bugs to popup: corrected.\r\n    For issue \"Add support for translation of the strings\", for the moment I removed the French translation. All is in English now. Code for translation are already incorporated. Waiting for translation files.\r\n\r\n    ### Release 1.0.8.1 :\r\n    -Internal code for B-spline modified, Radius replaced by Weight, initial Weight is now 1 adimensional.\r\n    -Variables in Tableau_pilote displaced and modified accordingly, variables Poids_entree and Poids_sortie.\r\n\r\n    ### Release 1.0.8 : \r\n    - Implements surfaces with better tangent continuity at leading edge. \r\n    - Modifies slightly user interface (some names are changed)\r\n    - Solves minor bugs\r\n    - Optimises the structure of the code\r\n    - Previous files are not compatible. From Interface_Usager, you simply have to transfer data from the sketch Meridien (12 2D points) and the spreadsheet Tableau_Pilote (copy-paste). And, of course transfer data from the FeaturePython Parametres.\r\n    - Be sure to update Curves WB\r\n\r\n\u003c/details\u003e","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsimturb%2Fbeltrami","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsimturb%2Fbeltrami","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsimturb%2Fbeltrami/lists"}
