[MITgcm-support] MITgcm-support Digest, Vol 172, Issue 5

Fri Oct 20 14:49:00 EDT 2017

Hi Raheleh,

You can include multiple ptracers in your simulation by explicitly specifying the tracer names/initial files in your data.ptracers file,

e.g.,

PTRACERS_numInUse = 3,

PTRACERS_names(1) = ’tracer1',
PTRACERS_names(2) = ’tracer2',
PTRACERS_names(3) = ’tracer3’,

PTRACERS_initialFile(1)='tracer1.bin',
PTRACERS_initialFile(2)='tracer2.bin',
PTRACERS_initialFile(3)='tracer3.bin',

Post your data.ptracers file if you are still having trouble after trying this,
Dustin
