This figure shows a snapshot of a scale-resolving simulation from NASA's 'Common Research Model' in a high-lift configuration, which was carried out using the previous standard CFD solver for external aerodynamics, TAU (in future, the standard will be CODA). Depicted are the isosurfaces of a common vortex detection criterion (Q-criterion), which are coloured with the local Mach number. They enable the visual observation of large-scale vortex phenomena and their interactions (for example, in the wake of the engine nacelle) and the identification and evaluation of small-scale turbulent structures within the framework of scale-resolving simulation.
Modern numerical simulations and high-resolution sensor systems produce increasingly large volumes of data. The amount of data is now so extensive that a subsequent analysis is both costly and time-consuming. Insufficient local resources, the complicated or non-existent access to remote high-performance computing (HPC) systems and the limited scalability of the software tools are all major challenges to efficient analysis. The lack of options for conducting efficient and effective data analysis and visualisation limits the degree to which the generated data can be exploited.
Visualisation of mantle convection simulations
Visualisation and analysis of ascending and descending material in Earth's mantle using CosmoScout VR software.
The VisPlore project oversees the development of a data analysis and visualisation platform. This will involve the establishment of a distributed software infrastructure within DLR, which will enable the efficient analysis of large scientific datasets using interactive visualisation methods.
Use cases:
High-resolution transient simulations from the field of aircraft aerodynamics and/or wind turbine aerodynamics.
High-resolution transient simulations of a turbomachinery configuration with periodic boundary conditions and which generates higher-order data.
Analysis of global and regional climate-chemistry simulations over longer time periods.
High-resolution transient convection simulations of the rock mantle and liquid iron-rich core of a rocky planet.
Multi-sensor time series from Earth observation data for floods with H3.
VisPlore is embedded in the 'Data' research area and addresses the section of DLR’s Digitalisation Strategy concerning the generation, management and use of valuable data.
The project will significantly advance the quality of generated data resources while also improving how data is managed by means of distributed storage and transparent access. Finally, the use of this data will be enabled through local, interactive visualisation and the connection to high-performance infrastructure.
