Peter & Freddie, I believe the mesh export issue from Pointwise using the PyFR exporter has been resolved in PyFR 1.6. I still seem to have issues running using the OpenCL backend which persistently complains about an invalid workgroup size. It use to work at one point, but something has changed in the intervening releases which is causing problems for me at least. I’ve tried adjusting the values per Freddie’s guidance to no avail. He also suggested a tool that might be helpful in determining the appropriate workgroup size needed for my card. Unfortunately that tool seems to be NVIDIA card specific requiring installation of NVIDIA software that won’t run on my machine. I’m using an AMD card instead, and the tool won’t compile due to missing dependencies. It’s not a pressing matter, but just something that I thought you both might want to be aware of. Nikki, I’ve looked over your incompressible 2d-cylinder case, and I was wondering if you could elaborate a bit, or point me to some reference, about how you came up with the source terms you’re using in the input file. It also appears that the [soln-plugin-pseudostats] is used in place of the [soln-plugin-residual] namelist for incompressible cases—is that right? Does the [soln-plugin-fluidforce] namelist still work for the ac-navier-stokes solver? Another question if you don’t mind—what is this artificial compressibility factor, ac-zeta and why is value of 6.0 used? Oh, and what does the ac prefix stand for? Thanks! I think it would be interesting to see how coarse of a higher-order mesh could be made for this case while increasing the polynomial solution basis such that you essentially recover the linear mesh spacing in each element, and see if you could capture one or more vortices within a single element with any noticeable diffusion over time.
