    بسم الله الرحمن الرحيم




    لكل فرع من فروع الهندسة مجموعة من البرامج تساعد المهندس في عمل الحسابات و التصميمات اللازمة ، و الفائدة القصوى من هذة البرامج هي توفير الوقت و تنظيم قواعد البيانات.


    و للهندسة البحرية بجميع فروعها العديد من البرامج المتخصصة التى لا يستخدمها غير المهندس البحرى..... كما أن من الممكن للمهندس البحرى إستخدام برامج غير متخصصة و لكنها قد تؤدى الغرض المطلوب ، و من أمثلتها :



    Autocad


    3d Studio Max


    SAP

    Microsoft Office

    و لكن حديثنا سيكون عن البرامج المتخصصة فى الهندسة البحرية ، و سنقوم بتقسيمها لتسهيل التعرف عليها.

    و هى عبارة عن باقة من البرامج تستخدم فى عمل حسابات تصميم و تحليل بيانات السفن







    تتكون باقة autoship من عدة برامج أشهرها:


    Autoship hull design/surface modeling program combines the graphical user interface of Windows with the dexterity of NURBS mathematics, the high-end CAD standard for surface modeling. Autoship enables you to create any hull shape from a racing yacht to a super tanker quickly and efficiently. Surface edges may be attached to a curve or another surface. Several methods are available to create a surface, such as by specifying dimensions, by rotating a curve about an axis, by extruding a curve along a vector, by sweeping one curve along another, by ruling between two curves or by multiconic development (developable surface) between two curves. Models may be exported and imported in 2D or 3D via industry-standard DXF and IGES file formats.


    و يستخدم عادة فى تمثيل سطح السفينة و عمل ال ship lines
    و تستطيع من خلاله عمل نموذج للسفبنة يمكن تحويله إلى برنامج Autohydro لعمل حسابات الإتزان.
    و لكن يراعى أن ليس كل النماذج المنتجة فى Autoship يمكن تحويلها بنجاح إلى Autohydro



    Autohydro is a complete hydrostatics and stability calculations program for naval architects, ship designers and marine engineers and reports the reaction of the model to various conditions, such as a loading configuration, a damage situation, conditions involving outside forces, wind or high speed turning momentum or some combination of these. Autohydro can also be used to obtain hull form characteristics and capacities.


    يستخدم لعمل حسابات إتزان السفينة سواء فى حالتها السليمة Intact أو فى حالة الضرر Damage
    يمكنك من إنتاج المنحنيات الهيدروستاتيكية Hydrostatic Curves و أيضا Cross curves & statical stability curves و به العديد من المميزات الأخرى.



    Autopower's advanced user interface enables optimization of hull parameters based upon twelve independent resistance and propulsion methods. Features: 8 methods for displacement hulls, 1 method for semi-displacement hulls, 2 methods for planing hulls, 1 method for catamarans and propeller optimization. Methods based on empirical studies and approved tank methods. Analysis of 5 models concurrently. Hull parameters may be generated by Autoship.


    تستطيع من خلاله حساب مقاومة الماء لجسم السفينة و تحديد السرعة و قوة المحرك المطلوبة و نوع الرفاص.








    باقة MaxSurf هى المنافس التقليدى ل Autoship و من أشهر برامجها:



    Maxsurf provides fast, flexible and intuitive modelling of all types of hulls, superstructures and appendages. An unlimited number of trimmed NURB surfaces can be used to model any vessel from yachts to workboats to the largest ships. Any number of NURB surfaces can be joined, trimmed and manipulated to create a complete model ready for hydrostatic analysis or construction detailing. Maxsurf provides automated transformation of the hull form to match desired dimensions and hydrostatic properties. Maxsurf provides a range of flexible tools for evaluating curvature of the entire surface as well as curvature along a particular surface contour such as a waterline or diagonal.

    Span provides sailing performance analysis for yachts in a variety of sailing conditions and produces performance polar curves to show predicted speeds. Using calculation methods similar to the original IMS Velocity Performance Prediction Program, Span solves the equations for lift and drag for hull and rig and finds an equilibrium velocity and angle of heel. Span's calculations operate through a variety of true wind angles and speed and calculate with both spinnaker up and spinnaker down.

    The FreeShip modelling kernel is purely based on subdivision surfaces. It uses a mixture of loop subdivision and Catmull Clark subdivision surfaces called quad-triangle subdivision. This enables the user to design the most complex surfaces with only one surface. Controlpoints can be added in areas only where they are needed. Holes and knuckle-lines are easily incorporated. The number of controlpoints may be drastically reduced compared to classical NURB surface modelling. Intersectionlines such as stations, buttocks and waterlines may be added to the model and are updated realtime when a controlpoint is being dragged. Adjustable precision by controlling the subdivision level. An Integrated shading engine provides stable software rendering without the need for 3rd party software or dll’s. As the name imply this software is a free and open source one!

    The FreeForm approach to modeling is like no other 3D modeling package you have ever used. It leverages your sense of touch to control basic tools that mimic sculpting and foam cutting. At the same time FreeForm modeling provides digital advantages and workflow capabilities that you expect from a computer application.




    Rhinoceros can create, edit, analyze, and translate NURBS curves, surfaces, and solids in Windows. Rhino has limited support for polygon meshes. There are no limits on complexity, degree, or size. extremely fast 3-D graphics, unlimited viewports, working perspective views, coordinate read-out, named views, named construction planes, customizable icons and user workspace... Rhino was designed to run on ordinary Windows desktop and laptop computers and no special graphics cards are required.

    Computational Fluid Dynamics


    Primary purpose ship based CFD codes is the minimization of wave making resistance. Visualization of the computed results gives a clear view of all features of the wave pattern, hull pressure distribution and streamline direction over the hull. Analysis and expert judgment then indicate which modifications of the hull form will reduce the wavemaking. In a few steps a hull form can thus be optimized efficiently and quickly. Additionally, the predicted pressure distribution may indicate possible improvements from the viscous resistance point of view (e.g. reduction of flow separation). The flow direction on the hull can be used for aligning bilge keels or knuckle lines with the local flow. Predicted far-field wave heights are relevant for wash.

    Ship Hydrostatics & Stability


    The most common analysis needed by any marine vehicle designer. Stability analysis programs are very good tools for solving any floating thing. Some of them can handle harder tasks such as multihulls and damaged stability conditions. They can also help for dealing longitudinal strength problems. In general they are easy to learn, use and understand for any naval architect - marine engineer.
