Hello!

I encountered the following problem (for me) when playing around with the new solve-relax functionality:

modelling a tunnel (basically like tutorial 1) and using the top heading / bench geometry & rockmass properties from tutorial 7 I observe that when I am using solve-relax for the excavated top heading alone I get a max. total displacement of 0.0452m and if I use it for an excavated full face (i.e. excavate top heading & bench) I get a max. total displacement of 0.0439m.

If I do the same with the "normal" solve function and I solve to equilibrium, the top heading alone shows 0.276m - and the full face excavation 0.544m of max. tot displacement.

Where the "normal" solve function produces results as I would expect them (the bigger the hole, the bigger the deformations...), I don't understand what the reason is that the solve-relax function produces equally big displacements for both excavation geometries (the top heading even slightly bigger than the full face !?).

A sample script is attached to this post and I'd highly appreciate any help!
