IP	Identification number of the node where the force is to be applied
FILENAME	Path and name of the external file listing the dynamic loads data.

External data file format:

The format of the external data file is as follows:

TIME(0) FX(0) FY(0) FZ(0) MX(0) MY(0) MZ(0)
TIME(1) FX(1) FY(1) FZ(1) MX(1) MY(1) MZ(1)
TIME(2) FX(2) FY(2) FZ(2) MX(2) MY(2) MZ(2)
...
TIME(N) FX(N) FY(N) FZ(N) MX(N) MY(N) MZ(N)

The number of rows is unlimited.

FX, FY and FZ load components are expressed in Newton.

MX, MY and MZ load components are expressed in N.m.

Note

During the first period this expression is multiplied by a factor t/RAMP in order to provide a progressive application of the prescribed loads (see keyword *RAMPTIME)

Example :

*FLOAD
1 C:\PATH\forcefile.txt

Node 1 is loaded with a time varying efforts defined in the ASCII file forcefile.txt.
