Dear Sir or Madam, I am writing to inquire about the frequently NaN check error in the "inc_cylinder_2d". As a newbie of PyFR, I used to try to change the Reynold number of the example by editing the "Uin". The default Reynolds number was 125 and the NaN check errors occurred only when the ...

Dear developers and dear fellow pyFR users, I have a few questions concerning the data location in high order cells as present in pyFR and the calculation of the dimensionless wall normal distance (Let's call it y+ from this point on) accordingly. 1) Calculation of y+ To calculate the y+ value ...

Hi, When I look at the couette_flow_2d.ini, I see that the backend-openmp is blank. Also there is no [backend-cuda] entry. So, is the command pyfr run -b cuda -p couette_flow_2d.pyfrm couette_flow_2d.ini correct? Regards, Mahmood ...

Hi all, I'm new to the high-order CFD world. I just have started playing around with PyFR and was hoping to implement Smagorinsky SGS model in the code. This model requires velocity gradients which I think are being calculated in flux calculation of navstokes solver (pyfr/solvers/navstokes/kern ...

My question may likely be addressed to Freddie. Previously, I had been running the clang-omp compiler with PyFr as the cc compiler in order to use OpenMP as a backend.. Apparently clang-omp has been deprecated, since OpenMP has been rolled into the main llvm branch. I have installed libomp, ...
