OGS general questions

Dear all,

I am a new OGS user and have the following questions:

  1. Is the documentation for OGS5 still available?

  2. I want to simulate saltwater intrusion in the subsurface and infiltration from surface to subsurface. The following processes are of interest: (i) subsurface processes with variable density flow. (ii) surface processes coupled with subsurface processes. Is this possible in OGS?

  3. I have received OGS5 input files and want to convert them to OGS6 input files. Is there an automatic tool for this process?

Since I am a new user, I would greatly appreciate any links, resources, articles, or information about the above questions.

Thank you!

Best Regards,
Radhakrishna. B.L.
