The COMFORT project is funded by the Independent Research Fund Denmark (DFF) through a . The project will reduce the time-to-solution of computational morphogenesis for time-dependent problems by at least an order of magnitude. We are pushing the field into a new era, paving the way for fundamental insights into optimal design of complex time-varying fluid devices, with applications in wind energy production and noise reduction, and cooling of high energy-density electronics.
We are achieving reduced time-to-solution by developing specialised computational methods for diffusion heat transfer and incompressible fluid flow problems with large variations in coefficients. By considering time as just another dimension like space, we discretise in all dimensions simultaneously and apply an “all-at-once” approach to solve the full time-dependent system. Amdahl’s law dictates that better efficiency is achievable by parallelising the entire solution process in space and time simultaneously.
Using different parallel-in-time methods we have so far shown speed-ups for heat transfer of up to 5x using a and up to 52x using a Using the space-time approach, we were able to optimise problems up to 4.2 billion degrees-of-freedom in just 17 minutes on 64 thousand cores.
