A function that automatically calculates and applies the water pressure on an element boundary line or surface.

Select the element boundary edge or surface where the water pressure will be applied. The [Auto] option can be used when the water level is pre-set, and it is used to automatically calculate the hydrostatic pressure based on the height difference between the water level and element boundary edge/surface. Use the [Manual] option to directly specify the water pressure size applied on the selected element edge/surface.
