<p class="MsoNormal">Hi, MITgcm users<br>
I wanted to increase viscosity in an adjoint run by setting up <br>
viscFacInAd in data.autodiff, and then I was asked to specify <br>
viscA4Dfile/viscA4Zfile in data. Could any tell me how to have <br>
viscA4Dfile?? below is the info written in the manual, but I do not <br>
know how to generate it.<br>
<br>
Best,<br>

filename for 3D specification of lateral biharmonic viscosity <br>
(divergence part) (m4/s); requires #define ALLOW_3D_VISCA4 in <br>
