I notice that in [soln-plugin-integrate] , integrate quantities are calculated every nsteps time steps, while when I use time controller, the time steps are not fixed value. I want to get integrate quantities at set intervals , what can I do ?
No this feature isn’t supported in PyFR. The issue is that when using adaptive time stepping, there is no guarantee that you’ll reliably be bale to get the exact dt you want.
For most purposes I find the current implementation to be sufficent. If you really need equally spaced data in time, given than in most conditions the global integral of a property will be continuous in time, you can straightfowradly apply a cubic spline of similar to interpolate the integrated values.
