Envenio has officially unveiled the theory manual for its affordable cloud based CFD solver, EXN/Aero. The theory manual aims to provide the user with details regarding both the theoretical set-up of the software, as well as describing the equations of fluid flow solved by EXN/Aero.
With more and more software engineers making use of the on-demand, cloud-based solver, including a number of international clients, the team is keen to promote its best practice. This theory manual is just one way that users can be sure they are making full use of EXN/Aero, enjoying the flexibility and full capability provided by this exciting solver.
The theory guide is easily accessible online, and has been split into easy-to-follow sections. Written by the Envenio development team, the theory manual not only provides new users with an overview of EXN/Aero-solved equations, but is also a useful reference to ensure long-term users get the most out of the solver.
The EXN/Aero solver utilizes a hybrid multiblock approach where structured and unstructured mesh regions are concurrently solved in their native data format, preserving the inherent benefits of each type. This allows EXN/Aero to better exploit CPU and GPU resources, playing to the strengths of a heterogeneous compute architecture layout.
EXN/Aero’s true multiblock approach also allows the user to specify the computational precision of each block. In this way, double precision can be applied only where it is needed (e.g. boundary layers), while other areas of the mesh operate in single precision (e.g. far-field mesh). This approach minimizes the memory footprint and increases performance relative to an all-or-nothing double precision approach.
