Mr. Maurizio Rosson

Hi all, I'd like to post-process CFD analysis results from FS-Flow software (formerly Futureship and now DNV-GL). Maybe I'm wrong, but I was able to import a set of .tp files with a previous CAESES version some months ago. Today I tried again but it doesn't work. From FS-Flow I can only export .cgns and ASCII Tecplot files. Could you please help me or explain if something is changed with the last CAESES release?

Hi everybody, I post this topic because I guess that people in FRIENDSHIP SYSTEMS know the FutureShip FS-Flow panel code well and I'd like to improve my hullform design procedure and analysis. I work for a small Italian company, active in marine vehicles field and with a leading position in Ro-Ro ships design - but not limited to. About CFD analysis before and after tank tests, I've been using FS-Flow panel code since 2010. Hullforms are designed with LINES (AVEVA-TRIBON) or DELFTShip, the latter allowing different designs quickly - a perfect fairing is not required at this stage. No parametric hullform design - and in the future I'm going to explore CAESES-FFW for that. Back to my question, the usual procedure is: - hullform design with DELFTShip (subdivision surfaces method) - exporting from DELFTShip (IGES format) - rebuilding with Rhinoceros - exporting from Rhinoceros (IGES format) - importing in FS-Flow The procedure is very tricky because of IGES geometry problems. When exporting an IGES format, DELFTShip tries to 'translate' the subdivision surfaces with less IGES surfaces as possible, but the geometry results in a set of dozens, hundreds of patches (and the quality is not so good, a lot of small holes or overlapping edges). That's a nightmare for FS-Flow: I should create more PolySurfaces and apply the correct orientation to a very, very large number of surfaces! So I rebuild the hullform in Rhinoceros with a network of curves (stations, buttocks and waterlines), also creating more 'groups' for different panel meshes (bulb, middle body, aft...). I wonder if CAESES-FFW CAD tools could allow me to import and manipulate the IGES model from DELFTShip in order to obtain a simplified set of IGES surfaces. Moreover, I'm interested in the SHIPFLOW format (.shf): I guess it's the same .shf input format for FS-Flow. Is there any tutorial or sample about that? What are your suggestions? The next step is connecting CAESES-FFW to FS-FLOW. I hope some experienced users can share their know-how.
