[MITgcm-support] MIT with OpenAD

[Abhisek Chakraborty]

Respected Dr. Patrick Heimbach & Dr. Jean,

I requested Thomas Kaminski (one of the TAF developres at FastOpt) for
an access to TAF, however he informed me about paying 10,000 Euro for
the non-commercial use of TAF, he didn't mention about trial license
or something like that. Now at present, my organization cann't pay
such a huge money.

So, I think, I should opt for OpenAD. I have downloaded OpenAd and
working on building it.

I need guidance from you and Jean to link MITgcm with openAd
(preferably some step by step guidelines).

Thanking in advance,
Abhisek
