All, I was interested in running a compressible simulation with PyFR. The target Reynolds number would be 2.146e+06. A p4 mesh would likely consist of around 15e+06 hexes. Freddie’s spreadsheet, if I’m reading correctly, estimates a 3-D double-precision Navier-Stokes problem would require 3.7e+13 bytes or 35.2GiB of memory to run. Again, correct me if I’m wrong, but if I recall the tilmestep should be somewhere between 1/p and 1/p^2 which would be between 0.25 and 0.0625 for a 4th order simulation. Ideally, I would like to run this out to steady state.
AWS has p3 instances with 1, 4, and 8 NVIDIA V100 cards available each with 16GB of memory, 5120 CUDA cores, and 7TFLOPS of double-precision performance. Is this problem tractable in the latest PyFR release? Does PyFR provide an inlet boundary condition where a total pressure and total temperature profile can be specified?
