I am checking tank design (pic 1) and expecting to get at least 200 mPa pressure at the bottom. ( hand calculation) . In pic. 1 the model is show about 20 mPa and other part of bottom over stressed. In pic. 2 I have only simply bottom part (pic 2) and results looks like close to hand calculation.
Could somebody help me why in full model result is different? Thanks in advance!
