Plugin for PyFR to compute global quantities for the test case Taylor-Green Vortex

General

Dear all,

First of all, I’d like to ask you whether you have run the test case Taylor-Green vortex with PyFR.

If so, I presume you have implemented a the plug-in for PyFR to compute the global quantities needed to validate this test case: integrals of kinetic energy, dissipation rate of energy, enstrophy.

If so, Would it be possible for you to provide me with the sources for this plug-in?

Thanks in advance.

Best regards,
Antonio

Hi Antonio,

First of all, I'd like to ask you whether you have run the test case
Taylor-Green vortex with PyFR.

Yes.

If so, I presume you have implemented a the plug-in for PyFR to compute
the global quantities needed to validate this test case: integrals of
kinetic energy, dissipation rate of energy, enstrophy.

If so, Would it be possible for you to provide me with the sources for
this plug-in?

To the best of my knowledge, and whenever I have run the case, the post
processing has always been performed by a separate script as opposed to
a plugin. Of course, it is absolutely possible to write a plugin for
this task and, indeed, should not be too difficult.

Regards, Freddie.

Dear Freddie,

Thanks for your reply.

But to my knowledge, in order to monitor the temporal evolution of quantities like kinetic energy, dissipation rate of energy, enstrophy, … one should do directly in PyFR, since otherwise you should write the *.pyfrs every few iterations, right?

In such case I will develop a simple plug-in for this following the examples provided in the sources.

Thanks a lot Freddie,

Best regards,
Antonio

An update on this, on the develop branch there is support for an integrator plugin that can integrate user defined expressions from the .ini file over the domain. See PyFR/develop.
