Description
The PRESSURE option should be used when a UNIFORM pressure
needs to be specified. The uniform PRESSURE may be provided
on the entire element or a user specified portion of the element
(defined by x
1
, y
1
and x
2
, y
2
- see description below). If x
1
, y
1
and
x
2
, y
2
are not provided, the pressure is applied on the entire
element. If only x
1
, y
1
is provided, the load is assumed as a
concentrated load applied at the specified point.
The PRESSURE may be provided either in GLOBAL (GX, GY,
GZ) directions or in local Z direction (normal to the element). If
the GLOBAL direction is omitted, the applied loading is assumed
to be in the local Z direction. The loads are proportional to the
area, not the projected area.
