> If you want to do operations on the whole solution across elements, I don’t think you can do this through the kernels. You may have to try it through the plugins which can access/modify the whole solution but it can be very slow.

Hello, @tdzanic,

I want to get whole solution across elements, as you said, mybe I need the plugins. Are there examples of plugins in pyfr? Could you give some more details?

With best regards
