Hi Jihee yoon,

It appears you are looking for applying Pressure by ‘surface effect’ and ‘Direct’ option.

Using ‘Surface effect’ option creates overlapping surf152/153 elements on the faces/edges and pressure is applied on it. The ‘Direct’ option applies the pressure directly on the solid/shell elements. They should produce similar result for a load. If you have multiple loads with direct option, then only last applied load is considered. But if you apply multiple loads with surface effect option, the resultant pressure will act on the structure.
