Hi Lauri,

Try removing Standard Earth Gravity in Step 1.  Most of the stress in the structure will come from the Hydrostatic pressure.  The self-weight of the structure may be insignificant compared to the weight of the fluid. What is the weight of the structure compared with the weight of the fluid?

Please show the Tabular Data for the Hydrostatic pressure and the Details window for this load and some graphics for the structure.

Regards,
Peter
