Comment regarding simulation proceedure to obtain data for POD analysis

For validation purposes perhaps it is a good idea to do an uncontrolled case at some stage.

Also for the POD analysis that I would eventually like to apply to this data, it is preferable if I can get data during the transition period from the uncontrolled state to the controlled state. That is to have a simulation at which firstly the uncontrolled state is statistically stationary, and then turn on the control. A series of instantaneous velocity and pressure fields (snapshots) will be written until the new controlled case is achieved.

It is not obvious how many convective time scales (non-dimensional seconds) are required to achieve the new controlled state, nor is it obvious what the fundamental frequencies (if any) will be present. It is therefore not obvious what the write interval or how many snapshots we need during this period. We could either write out an excessive amount of snapshots or do the simulation twice. I think the latter is a better option, particularly if we initially concentrate on a smaller mesh as discussed previously.

Data formats

Is it possible to convert the data to a VTK format?
