Aerospace and Lightweigh structures
Our team of specialists takes pride in being at the leading edge of aerospace and lightweight structures research in Finland. Our long cooperation with the Finnish Air Force has been a catalyst for continuous improvement of our analysis methods. In particular, our in-house CFD code FINFLO has had a vital role in fighter jet analysis for FAF.
Since 2014, our team has also been working on the MetNet Mars Lander in cooperation with the Finnish Meteorological Institute. This project requires extensive simulations in the Martian atmosphere, testing our capabilities for atmospheric modelling.
The FINFLO solver is based on Reynolds-averaged Navier-Stokes equations. Reynolds averaging is practically the only way to handle the effects of turbulence in technical applications. Using Reynolds-averaged equations, several strategies can be employed to model turbulence.
FINFLO can be used to solve both compressible and incompressible flows. The code is based on a structured multiblock grid topology. Geometry modelling can be enhanced by a Chimera technique and discontinuous block interfaces, while a multigrid technique is used to accelerate convergence. The code has been parallelized using the MPI standard to allow it to be run on supercomputers and PCs. Turbulence modelling can range from the k-epsilon and k-omega-SST models to full Reynolds stress closure.
Finflo has also developed Finflotools, an extensive package of auxiliary programs for use during pre- and post-processing, to monitor convergence and set boundary conditions, for example.
