    Notes: As computer simulation increasingly supports engineering design and manufacture, the requirement for a computer software environment providing an integration platform for computational engineering software increases. The potential benefits to industry are considerable. As a first step in the long-term development of such a system, a computer software environment has been developed for pre- and post-processing for unstructured grid-based computational simulation. Arbitrary computer application software can be integrated into the environment to provide a multi-disciplinary engineering analysis capability within one unified computational framework. Recognising the computational demands of many application areas, the environment includes a set of parallel tools to help the user maximise the potential of high performance computers and networks. The paper will present details of the environment and include an example of, and discussion about, the integration of application software.

    Notes: In an arbitrary assembly of triangles or tetrahedra there is often a requirement to recover or construct edges or triangles which are formed by the connections between nodes. Such is the case in computational methods where grids of triangles or tetrahedra must conform to prespecified boundaries. Discusses general techniques which can be applied to recover edges and triangles within unstructured assemblies of triangles and tetrahedra. The methods described involve the intersection of the required edges and triangles with other nodes, edges, triangles and tetrahedra and then locally performing transformations of the element connectivities. The method is applied to the recovery of fixed boundary triangles for finite element meshes and to the construction of multidomains within unstructured grids. Several applications of the method are given to real practical problems.

    Notes: A general philosophy is presented in which all the modules within the computational cycle are parallelised and executed on parallel computer hardware, thereby avoiding the creation of computational bottlenecks. In particular, unstructured mesh generation with adaptation, computational fluid dynamics and computational electromagnetic solvers and the visualisation of grid and solution data are all performed in parallel. In addition, all these modules are embedded within a parallel problem solving environment. This paper will provide an overview of these developments. In particular, details of the parallel mesh generator, which has been used to generate meshes in excess of 100 million elements, will be given. A brief overview will be presented of the approach used to parallelise the solvers and how large data sets are interrogated and visualised on distributed computer platforms. Details of the parallel adaptation algorithm will be presented. These parallel component modules are linked using CORBA communication to provide an integrated parallel approach for large scale simulations. Several examples are given of the approach applied to the simulation of large aerospace calculations in the field of aerodynamics and electromagnetics.
