BOCHA
Force distributed on the boundaries of a plane element
Description
This element applies a normal pressure P on the parabolic or lineic borders of an element. Each border is defined by 2 or 3 nodes. The positive axis for pressure is on the left when considering the element in the order of the nodes.
The forces are defined by the fictive law BOCHA.
