REMARKS It is an action keyword placed in either an automatic script file or in a Master file. The purpose of PROBID is to set the problem id during the processing of a master file in order to specify the database to be read and or written to.

REMARKS Pressure is defined as force per unit area. The pressure is assumed to be linear between adjacent nodes as shown in Figure 6.9 on page 6-68. The pressure constraint will be applied to the element faces lying between the selected boundary nodes. The pressure direction may be specified as normal or shear. Positive normal pressure applies tension to the element faces. Positive shear traction is defined by the right hand rule. If no value is specified for DefPressureX DefPressureY or DefPressureZ it is assumed to be zero. Nodal pressure values may only be applied to
