I'm lost!

I'm not yet an engineer...but if my lifework will be like my schoolwork, I can't do this a long time!!!

If I change who is slave and who is master in my LIAISON_MAIL, I have various results... some seems to be good, some not!
If I put DNOR in DDL_MAIT and DDL_ESCL, new results good or not!

How can I simulate the real state of my wall!

Wall construct in earthern building method (pisé).
Portico (beam/poles) in wood to take the roof and to lower the reactions in the wall!

Who is master? Who is slave?

The beam is in contact with all poles and the wall!
Three poles are included in the wall - How can I give forces of friction in the wall?

If anyone have an idea and can help me, it'll be very helpfull!!!

help?
