#UFOCFD (octree) demo of Tesla Model 3 geometry. Animation shows the solution development over 20k iterations. The rapid #automeshing generates 1M cell mesh in seconds before the solver starts. Rotational velocity applied to the wheel surfaces. All post-processing using #Paraview
#UFOCFD (octree) quick test of new variable surface refinement feature (VSR) flow solver at V=200m/sec #Tornado geometry ...only 1000 iterations (not fully converged) #automeshing creates 0.5 million cells. Meshing and VTK file write takes only 8 seconds. #simulationFriday
#UFOCFD (octree) benchmarking - 10.5M octree cells in 140 seconds, that includes 20 seconds writing the VTK file for #Paraview. Background mesh level 4, #AudiR18 surface level 12. Peak RAM = 6.5GB. The #automeshing is serial, but the solver is #OpenMP parallel #simulationFriday
#UFOCFD (octree) just done another run of the #Audi R18 e-tron quattro testcase, this time with global time-stepping (not local) and some extra wake refinement downstream of the car. #Automeshing approx 2.3M cells, 40k iterations, 5.5 hours runtime, saving every 1000 iterations.
#UFOCFD (octree) simulation of #Audi R18 (e-tron quattro from #grabcad). #Automeshing gives approx 2M cells, solver did 20k iterations, taking 3 hours runtime, on 4 procs. Some checkerboarding - needs slightly higher smoothing value. #Paraview #simulationFriday
#UFOCFD (octree) santa and sleigh 100m/sec demo - approx 3M live cells - #automeshing takes 45sec before the flow solver begins, restarted from previous VTK solution, animation based on 180 VTK solutions saving every 100 iterations. Post-processing done with @kitware #Paraview
#UFOCFD (octree) #BACmono @discovermono at 75m/sec with camera orbit & animated streamlines using @Kitware #Paraview. #Automeshing gave 1.3 million live cells, solver did 18k iterations saving every 100its, allowing 2deg increments of the camera orbit. Needs some wake refinement!
Quick look at Mach 2.0 #Starwars #TIEfighter with #ufocfd #automeshing & @kitware #paraview for post-processing - approx 1million cells, 10k iterations, only 1hour of runtime. #MerryChristmas to one and all!
approx 500k live cells, 1M cells in total, #automeshing done in seconds before solver starts, 100m/sec #ufocfd #paraview
This #drivaer geometry meshes first time with #ufocfd #automeshing. No cleanup or hole fixing is required required because the geometry is already perfect for CFD. There are 10 octree levels giving 1.5 million live cells. Parallel solver run in progress - solution later today.
Modifying the #ufocfd (octree) solver to allow for main rotor and tail rotor discs on Lynx helicopter fuselage. Mesh only 360k live cells, runtime approx 40 minutes including #automeshing. Animation done with #Paraview.
#Lynx fuselage aerodynamics with #UFOCFD and #Paraview. The #automeshing takes approx 8 seconds, before the flow solver starts. The solver ran for 20k iterations in 55 minutes, the mesh size was 465k live cells. Animation shows streamline development during solution convergence.
#Lynx fuselage aerodynamics with #ufocfd (octree) and #Paraview. Looking at the wake development using velocity isosurfaces. The solver ran for 20k iterations in 55mins, and the mesh size is 465k live cells. #automeshing #simulationFriday
#UFOCFD (octree) with #automeshing used to study #Ferrari 488 wake aerodynamics. Mesh size approx 1 million cells - solver does 80k iterations - runtime 8 hours. Showing here isosurfaces of Qcriterion = vorticity - strain.
Post-pro done with @kitware #Paraview #simulationFriday
#Ferrari Dino aerodynamics with #ufocfd (octree) freeware - using extended refinement box to capture the wake region. Air speed 30m/sec - 12k solver iterations on 4 procs - runtime 30 minutes. Mesh size 0.8 million live cells. #automeshing takes only 10 seconds #simulationFriday
#Ferrari Dino aerodynamics with #ufocfd (octree) freeware. Air speed 30 m/sec. 20k solver iterations on 4 procs, takes 45 minutes. Mesh only 0.6 million live cells. #Automeshing takes only 10 seconds. All post-processing done with @Kitware #Paraview #simulationFriday
#Ferrari aerodynamics with #UFOCFD octree solver. 400k live cells, 10k iterations, 38mins runtime including #automeshing. All case setup and post-processing done with @Kitware #Paraview #simulationFriday
Further testing of the #UFOCFD octree solver with this AH-64 Apache geometry. Simulated air speed 30m/sec. Mesh 320k live cells. Solver runtime was approx 30mins for 10k iterations. The meshing is fully automated taking 5 seconds. @Kitware #Paraview #automeshing #simulationFriday
2nd demo of new #UFOCFD octree solver. 260k live cells, 5k iterations, runtime 12 minutes. #BACMono geometry at 30m/sec #automeshing #simulationFriday
