I found it is not possible to set the following Scenario.

----------------------------------------------------------------------------------------------------------

a. Applied Load:                         1000 N

b  Starting Load Factor              0.001  or (0.001 x 1000 = 1N),  structure is unstable at initial condition so that very small load is applied at first iteration)

c  Manual increment                   100 N (I want to plot displacement at every 100 N increment)

d  Iteration Limit:                           12 (if not converge after 12 iteration, step down to 0.5 x increment)

e  Max Load Factor:                       1.5  (I want to investigate till 1500 N)  

-------------------

The problem of ABAQUS, b = c,  Starting load factor is same as Manual increment. It causes very uneconomic analysis. 

It is possible in LUSAS. Any suggestion please.
