  • CAD data storage and access in IDAM [Elektronski vir]
    Telenta, Marijo ; Kos, Leon, 1966- ; Akers, Robert
    Integrated Data Access Management (IDAM) is a data access tool for analysis, visualisation, and modelling. It is developed at CCFE for MAST-U data access. Data access is based on data objects from ... within the files. IDAM is also put capable. Metadata from raw and analysed files is written to the IDAM database. The IDAM server uses a plugin architecture for each data resource type. The goal of the presented work is to build a workflow which will access and eventually store CAD data through IDAM. CAD data in IDAM has a single source, i.e. it is stored in a single location as CATIA files. A first step is to build a data resource which will include metadata and a catalogue design. This step includes categorising the resources and recording them to the IDAM database. The data resource will provide CAD data in a STEP format for two workflows. The first workflow is an engineering one, in which more complex 3D models are required in STEP format to be read by COMSOL and ANSYS and perform, for example, electro-magnetic numerical simulations. The second workflow is a scientific one, in which 2D axisymmetric section-cuts are performed on CAD models with dif- ferent levels of detail. The section cut is performed for a specific angle [phi] from the horizontal axis. These section-cuts are then converted/exported by a python plug-in to VTK/XML and used by the equilibrium physics code, EFIT++ developed by General Atomic enhanced at CCFE.. Attention is given to the definition of a structure in the STEP file in order to locate different components needed for the code. Generally, it is better to have one file to ensure the data provenance of the workflow. Better efficiency could be achieved with a zero-copy approach type movement, such that no unnec- essary copying of the STEP file is done. The second step is to develop an IDAM server plugin to get/put metadata for CAD data objects into an object store. This will serve the data through the plug-in. The IDAM storage includes collection and cataloguing of the metadata during the CAD data handling. This ensures that the CAD data provenance tracking and capture are together with other objects available in the IDAM.
