Hi guys, I am trying to define some velocity profiles in [soln-ics] using the expressions below. I think that it doesn't pass the 'if' and 'else' statements to the solver. Do you have some suggestions please? Any help would be much appreciated. Cheers, Andrei *if y<1.:* * yplus = y * ...

Hello all, Is there a "filter" that can render C0 continuous data from PyFR output (that is by definition discontinuous at the elements). Why? I'm trying to calculate PSD in space for Taylor-Green Vortex case and there occur peaks on wave-numbers corresponding to the element size. Kindly ...

When using hex elements with order say 4 or 5, the number of non-zeros in the GiMMiK kernels gets quite high. E.g., with n=4, tgradpcoru_upts [hex] appears to get 1819 non-zeros from 46875 entries (i.e. about 4% non-zeros) Just wondering, for high-order 3d runs, what's an appropriate way to ...

Hi all, I'm a first year PhD student and interested in calculating the volume integrals of expressions like (u.u + v.v + w.w) in the whole domain of Taylor-Green vortex problem. I'd like to do it within PyFR because I found that if I write the results and do the integrals in say, Paraview ...

Hello All, I am hacking around with PyFR trying to see if I can implement reacting flows into the solver. My first step has been to just get species mass fractions as passive scalars in the euler solver and implement mixture thermodynamics (i.e. calculate mixture Cp, Rg, Cv, etc. to then ...

Hi all, I’m a PhD student comparing PyFR to standard CFD tools in a hope to transferring high-order technology to industrial applications. As a start, I’ve recently tried to run 3D Taylor-Green vortex case (Re=1600, M=0.1 Ref:[1]) using compressible PyFR solver (PyFR 1.7.5). I’m running the ...

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.
