Hi, everyone
I am trying to use dual stepping with following settiing:
[solver-time-integrator]
formuation = dual
scheme = bdf2
pseudo-scheme = euler
tstart = 0.0
tend = 100.0
dt = 0.005
pseudo-dt = 0.001
controller = none
pseudo-niters-max = 20
pseudo-niters-min = 5
pseudo-aresid = 1e-5
pseudo-rresid = 1e-5
It turns out the following error:
[root@localhost dual]# pyfr run -b openmp -p ../euler_vortex_2d.pyfrm
euler_vortex_2d.ini ##39s
