Dear All, I'm trying to run PyFR on Xeon Phi 7250 (Knight Landing). There is only one Xeon Phi processor, and no CPU on my computing node. Therefore, I log in to the Xeon Phi from front-end node via ssh, and execute command on Xeon Phi directly. In this case, how I can write "backend-mic" ...

Hello all, From the documentation it seems that PyFR itself does not itself create periodic boundary conditions (i.e. define the required connectivity) and hence such must be specified already in the mesh file. In this regards, could folks mention how they create such boundary conditions? ...

Postdoctoral Position - GPU Accelerated High-Order Computational Fluid Dynamics
Summary: A fully funded Postdoctoral position is currently available. The project, will involve development of PyFR, an open-source high-order massively-parallel cross-platform CFD solver, as well as its application to solve a range of challenging unsteady flow problems. Candidates should hold, or expect to obtain, a PhD in a numerate discipline from a world-leading university.
