Dear Mr. Freddie,

I have corrected it as follow:
mu = 0.000004077
and got an another error.
These were the last lines of the error.
could you also please suggest what could be the reason for this.

Thank you and Regards,
Manu.

I suspect it is because you have:

[soln-plugin-turbulencegenerator]

which is a plugin that does not exist in PyFR.

Regards, Freddie.

Dear Mr. Freddie,

I took the PyFR code from the git link below:
https://github.com/GiorgioGiangaspero/PyFR/tree/turb_injection_SEM_localLTurb

and I referred following paper for the plugin – [soln-plugin-turbulencegenerator]
Synthetic Turbulence Generation for High-Order Scale-Resolving Simulations on Unstructured Grids

Regards,
Manu.

This is not an officially supported version of PyFR and provided as-is; you are very much on your own here when it comes to debugging.

Regards, Freddie.
