Description (last modified by arango)

The perfect restart option (PERFECT_RESTART) still needs some work. It is now working in 2D applications. For the soliton example, I get the following errors when compared with the control run:

Perfect restart activated:

Variable       RMS          Correlation

 zeta      1.72573635e-10  1.00000000e-00
 ubar      9.82710975e-11  1.00000000e+00
 vbar      8.24326868e-11  1.00000000e-00

NO perfect restart:

Variable       RMS          Correlation
  
 zeta      2.98162633e-06  9.99999987e-01
 ubar      2.44486068e-06  9.99999992e-01
 vbar      1.91947734e-06  9.99999942e-01

However, it is still not working in 3D applications like the upwelling test case.

John Warner fixed a bug in ini_fields.F and now we really get a perfect restart in 2D applicatioons. The errors in the soliton test case are now:

Variable       RMS          Correlation

 zeta      0.00000000e+00  1.00000000e+00
 ubar      0.00000000e+00  1.00000000e+00
 vbar      0.00000000e+00  1.00000000e+00

We are still hunting for a bug in the perfect restart for 3D applications.
