Ok thanks Richard/Habib that leads back to setting up the loadcases in a similar manner to that shown above by MUL211.

I guess the difficult thing is, it is easy to play with the load cases but harder to actually know the implications of doing so. Likewise for APIPE, we can tick a box saying do not use friction on seismic, but really have no understanding as to how this is in fact applied.Time for a leap of faith I guess.
