TCL Command TASK LOADP

Description

Definition of a pressure load on finite elements. The load is defined either by a corresponding surface object or by a docking point on the body to be loaded. If the load is not consistent but distributed instead, then the distribution must be specified by load points on the edge of the surface object or by a two-dimensional table to be defined. The load type is very similar to the LOADS loads type, but with LOADP, the direction of the load is defined by the normal direction of the surface to be loaded.

Arguments

The basic arguments correspond to those of all tasks (see TCL Command TASK). The other arguments must be entered in the form "key=value".

There are the following additional specific, predefined arguments:

Key	Value	unit	Meaning
q	qvalue	FORCE/(LSTRUCT*LSTRUCT)	Load value
qfact	tabname	TEXT	Dimensionless, two-dimensional table; the load value is determined by the product q * table(x,y). The origin of the table lies in the specified docking point.
lsurf	surfname	TEXT	Reference surface

TASK LOADS 1 LOCAL 0 18 "q=100.000" "qfact=TableXY((?1),{y=(?2)})" "descr=Pressure load"

In order to be able to enter the area load as a function of a set of curves, this set of curves must be defined in advance in Scope CALC. In this case, the set of curves "TableXY" consisting of 2 tables "tab1" and "tab2".

When applying the load q=100.0 then the load value is multiplied by the table value. The current arguments (?1) and (?2) result from the position of the load point. The origin of the table is located in the specified docking point (see Assembly).
