The development of component models to populate a proposed OpenModelica standard library for the ocean engineering domain is described through the process of modelling the response of catenary-moored wave-energy converters in the ‘free-to-use’ OpenModelica simulation environment and its associated OMEdit graphical user interface. A wave energy conversion concept is presented, followed by the implementation of Modelica component models and functions to simulate wave, current, and mooring loads on a cylindrical floating object. The irregular sea surface is specified using the Pierson-Moskowitz spectrum and the heave force on the buoy is determined based on the Froude-Krylov formulation. Mooring load formulation is based on the catenary theory. Combined wave and current loads on the buoy and on the mooring chain are arrived at using the Morison equation. The results are verified with the commercial software Orcaflex, and the preliminary OceanEngineering library is made available for download. The integrated simulation of the multiphysical wave energy buoy system is then carried out to determine the energy harvest potential, and results discussed. An alternative design is then suggested and simulated to demonstrate the advantages of using the component-based approach.

In this paper, the theory of progressive ocean-surface gravity-waves is discussed, followed by the concept of the representation of the irregular sea-state by a sea-spectrum. Fourier series decomposition of the irregular sea-surface into its constituent regular waves and the method of realizing unique time-records of the sea-surface-elevation from commonly used sea-spectra is described. A detailed description of the development of Modelica componentmodels to generate regular as well as irregular waves, and depth-varying current, with an eye on the requirements imposed by probable integrated simulation scenarios, is then presented and the results discussed.

Wave making forces are one of the important design criteria for offshore platforms. Linear or first order wave forces are well explained and offshore platforms are designed such that its natural frequencies of motion are well outside the first order excitation wave forces. But the effects of Nonlinear or second order wave forces are sometimes neglected since its magnitudes are less compared to first order ones. But the low frequency components of second order wave forces can cause slow drift motions of the platform, causing resonant motions of the platform. This work shows the numerical evaluation of second order wave force and its effects.

The whole pharmaceutical area (pharmacy industry, pharmacy billing, clinical trials, pharmacovigilance, and drug-drug interaction detection) needed various innovative and scientific solutions to solve the problems. A systematic review was performed on various software applications widely used in the pharmaceutical industry, including clinical trials, pharmacy billing, pharmacovigilance, the detection of drug interactions that assist the healthcare professional. Our review concluded that computer software has created a significant role in the pharmaceutical industry, pharmacy billing, and herbal industry. The computer software and programmes aid in reducing manufacturing costs, manufacturing errors, medical errors, and clinical errors.The software performs various safety functions, supplies on-screen access to pertinent drug and patient information, manages data, and assists in the product formulation process. The programmed safeguards can be modified to meet changing requirements.

In this paper, a new open-source implementation of the lower-order, 3-D Boundary Element Method (BEM) of solution to the deep-water, zero Froude-number wave-body interaction problem is described. A validation case for OMHyD, the new open-source package, is included, where the outputs are compared to results obtained using the widely used frequency-domain hydrodynamic analysis package ANSYS-AQWA. The theory behind the solution to the diffraction-radiation problem is re-visited using the Green function method. The Hess and Smith panel method is then extended to the case of a floating object using the image-source to impose the wall condition at the free-surface, and a wavy Green function component to account for presence of free-surface waves. An algorithm for computer implementation of the procedure is developed and subsequently implemented in PYTHON. The wavy part of the Green function is determined using a verified and published FORTRAN code by Teleste and Noblesse, wrapped for PYTHON using the Fortran to Python (F2PY) interface. Results are presented for the various stages of implementation viz. panelling, body in infinite fluid domain, effect of the free-surface, and effect of surface-waves. The hydrodynamic coefficients obtained from this preliminary frequency-domain analysis are shown to be in satisfactory agreement with ANSYS-AQWA results. Conclusions are drawn based on the performance of the code, followed by suggestions for further improvement by including the removal of irregular-frequencies, multi-body interactions, and bottom interference, which are not considered in the present implementation.
