*GRCONT,NAME=EXTLOAD

Data format:

Three lines with following parameters:

IGR IOP
DLLFileName
DLLProcName

Restriction :

Group must be previously defined. For dynamic analysis.

Purpose

To define external loads on a group of elements via a DLL

Details : | Parameter | Description | | --- | --- | |IGR | group number| |IOP| - IOP = 0: loads given in local frame (beam elements)
- IOP = 1: loads given in general frame| |DLLFileName | DLL file name| |DLLProcName | DLL procedure name|

Note

Procedure in the DLL exchanges the following information with DeepLines at the beginning of each timestep : (vect, pos, isize, time, dt) where:

  • vect is a double precision real matrix of length (6,isize) . The procedure provides forces/moments to be applied on the 6 degrees of freedom at each pos(i)

  • pos is a double precision real vector of length isize. DeepLines provides the arc length (m)where the loads are applied

  • isize is an integer to defined the size of the arrays.

  • time : times (s)

  • dt : timestep (s)
