Starting from a complete HB setup in TRACE.hb.start.cgns. In order to include some S1 planes for online processing and to compare the simulations, use the following POST command

POST -i TRACE.hb.start.cgns -rbc -db -famtype Boundary -ip -gf TRACE_S2.input -cf cuts.dat -o TRACE.hb.startAn.cgns

For further information about the definition of the S1 planes please see the POST user guide.

Start the HB simulation:

TRACE -cgns TRACE.hb.startAn.cgns -cntl TRACE_control.hb.input

To create a setup capable of a restart with BDF2 time stepping and without phaselag use the 3D Fourier output:

POST -i ../output/hb/cgns/TRACE.fourier.cgns -rbc -db -famtype Boundary -darf -pitch 22.5 -t 0.0 -o TRACE.unsteady.start.cgns

POST -i ../output/hb/cgns/TRACE.fourier.cgns -rbc -db -famtype Boundary -darf -pitch 22.5 -t -0.1 -rs -sol FlowSolution FlowSolutionPrevious -o TRACE.unsteady.start.cgns -as

Now the final solver setup using GMC:

gmcPlay configureUnsteadySimulation.jou

Now an unsteady simulation can be carried out:

TRACE -cgns TRACE.unsteady.start.cgns

For the comparision of the two simulations some S1 planes can be used, which POST included into the CGNS in the first step. TRACE included these plane in the 2D Fourier output. But in the case of the HB simulation the pitch the planes have to be duplicated to match the pitch of the unsteady simulation:

POST -i ../output/hb/cgns/TRACE.fourier_2D.cgns -dd -pitch 22.5 -icv -o ../output/hb/cgns/TRACE.fourier.plt

POST -i ../output/unsteady/cgns/TRACE.fourier_2D.cgns -icv -o ../output/unsteady/cgns/TRACE.fourier.plt
