NOTE: sometimes ParaView will make an error and write zeros where it can't quite find the closest point when doing the solution transfer. In this case, the .csv file needs to be manually edited to replace the zeros for pressure and temperature with realistic values.
 # The .csv file can now be reformatted and renamed with MATLAB to match the expected form of solInterp.1.

 to not take any  actual steps.  Note however that only very recent version of the code have the iexec conditional moved AFTER the loading of the interpolated solution but it should be pretty easy to figure out where to move that  conditional.   Alternatively, the second option also  skips over the time stepping and writes the solution  AFTER applying the boundary conditions which can be useful to see as well to confirm you have the intended BC’s set (iexec :0 won’t detect this)
