In Multiframe, steel water storage tank analysis using patches.

In Multiframe, I am not getting the expected results from a steel water storage tank analysis using patches. Does anyone have experience in modelling this type of tank?

    I tried both methods of modelling – generate tank and did it manually.
    I used the hydrostatic load case – yes.
     
    I am getting stress in range of nil to 120,500 MPa, which is much, much higher than feasible.
    I suspect I may have done something incorrect in model, but cannot see what it is.
