🎶On the twelfth day of CEEC-ness, my true love gave to me, Merchant ships a-simming...🎶 Unlike #aerospace, #Maritime doesn't commonly use high-fidelity #CFD simulations for design. CEEC will capitalize on new, larger #HPC systems to start catching up on simulations for ship modeling.
ceec-coe.eu/merchant-shi... 🎶...Nek code improvements, Atmo boundary models, Coupled waLBerla, Wind turbines eroding, Better Neko meshing, Fast static mixers, New SOD2D flows! solid Alya code, Plane wings that bend, FLEXI transonic flows, and an airplane that wants to fly free.🎶
🎶on the eleventh day of CEEC-ness, my true love gave to me, Nek code improvements...🎶 Nek has been around for decades, but hardware keeps evolving, which means Nek must too.
IN CEEC, we'll be both porting Nek to new hardware, such as for the Jupiter system from the @fz-juelich.de, as well as improving its large eddy simulations and wall modelling. ceec-coe.eu/nek5000-nekrs/
🎶On the tenth day of CEEC-ness, my true love gave to me, Atmo boundary models...🎶 Understanding or someday predicting our atmosphere has implications for solar energy, wind energy, urban modeling, and weather prediction (of course). These kinds of simulations have no upper limit ...
... in size or detail given that atmosphere covers our entire planet. In CEEC, we're pushing the state of the art in this field to make more accurate, larger simulations possible, even on the newest generation of European supercomputers. ceec-coe.eu/atmospheric-...
🎶On the ninth day of CEEC-ness, my true love gave to me, Coupled waLBerla...🎶 waLBerla uses the lattice Boltzmann method to simulate flow, unlike all the other CEEC codes that solve the Navier-Stokes equations.
For the lighthouse case where we’re using waLBerla, we’re simulating coupled micro erosion fluid flow and particle flow. In CEEC, we're therefore improving the performance of this coupled fluid – particle flow simulation. ceec-coe.eu/walberla/
🎶On the eighth day of CEEC-ness, my true love gave to me, Wind turbines eroding...🎶 Off-shore wind energy has great potential but also environmental impacts. One solution is suction mounting the turbine pylons, which is much quieter.
Erosion and micro erosion can cause suction pylon installation to fail, though. So, we’re building a simulation of this erosion to understand how to make suction installation more successful. ceec-coe.eu/localized-er...
🎶On the seventh day of CEEC-ness, my true love gave to me, Better Neko meshing…🎶 #Neko is incredibly fast and paralel as well as easy to use across hardware architectures, with it's abstraction layer that takes care of choosing the correct kernal for the system.
That said, it could be better at building meshes for complex geometries. That's one of the things we're working on improving to enable the two lighthouse cases where we're using #Neko - yesterday's static mixers as well as day 12 of this song parody being published next Friday. ceec-coe.eu/neko/
🎶On the sixth day of CEEC-ness, my true love gave to me, Fast static mixers...🎶 Static mixers, tubes whose internal topology mixes fluids without any moving parts,are therefore low maintenance and cost effective for many industries spanning medicine to food.
However, finding the best balance between speed of flow and thoroughness mixing is difficult. We're teaching #Neko to simulate this optimal topology! ceec-coe.eu/topology-opt...
