Hi to all!!

I've a big problem and I hope someone will help me.
I use caesarII v.5.10 build 080512

The problem is: I'm trying to do a complex simulation in which I have to consider displacement of structures, inertial accelerations.
The result I obtain, for my opinion, is affected by errors.
Below you can see load cases combination and result:

FY (force in axial direction)
L1=W+P1 64N
L2=W+P1+T1 1648N
L3=W+P1+D1 -11295N
L4=W+P1+T1+D1 9857N
L5=D1 -4852N
L6=T1 593N
L7=L2-L1 1712N
L8=L3-L1 -11231N
L9=L4-L2 -11505N
L10=L4-L3 1439N

W=weight
P1=pressure
T1=temperature
D1=displacement

Note combinations shown above are worked out to obtain T1 and D1.
I' think of L6,L7,L10(to obtain T1) and L5,L8,L9(to obtain D1) should have respectively same results, but it'isnt.

Why?

All results relate to the same node which is an ANC.

PS: I've also seen axial force on valves is much more high then in a node in which there is a restrain (i.e. valve in Y(axial)direction and the restrain in Z(vertical) direction).
