DEFINITION
ECPRES maintains a specified normal pressure across the face of the elements lying on the selected edge. Note that tangential pressures are no longer supported in this definition.
REMARKS
Pressure is defined as force per unit area. The pressure is assumed to be linear between adjacent edges. The pressure constraint will be applied to the element faces lying between the selected boundary nodes. The pressure direction may be specified as normal. Positive normal pressure applies tension to the element faces. If no value is specified for DefPressure, it is assumed to be zero. Nodal pressure may be specified as a function of time with keyword ECDEFN.
