ABAQUS UMAT SDVINI problem

I’m trying to write a UMAT code for unsaturated soil model and I need to define some state parameters. I found that I can do that by using SDVINI subordinate. Should I put it at the and of UMAT? How can I put *INITIAL CONDITIONS, TYPE=SOLUTION condition in input file?

Another question is ” is it possible to do a coupled analysis in ABAQUS?
for example: Hydo mechanical coupling of unsaturated soil mechanics.

Thank you.
Best regards,
