License File and Usage

The WorldSID is distributed with a license file which uses an expiry date. The license file is sent to the user with the whole dummy package. It is a PGP encrypted part of the dummy model input and includes all load curves referenced in the WorldSID model. For the WorldSID there is a general license file for any unit system provided.
There are parameters defined which can be used to offset the numbering of the load curves. The load curves can be scaled by using parameters provided in the main WorldSID input. The names of the parameters refer to the table or load curve ID of each material. So if the values of the table ID 1002 are to be scaled then the parameter ws1002 should be used.

The principle structure is as follows:

Input data in the WorldSID license file:

$ Load Curve offset
I wloff 0

$ Load Curve scale values
R wsXXXX 1.0
R wsxXXXX 1.0

Input of the license file:

I lcTABID TABID + &wloff
R eTABID 1.0 * & wsXXXX

&lcTABID 0 1.0&eTABID 0.0 0.0
<Values_x> <Values_y>


The license file must be included like a normal include file. But it is necessary that the license file is included IN the WorldSID model main file AFTER the *PARMETER block. If you get error messages like “missing parameter” you should check if the license file is included at the correct position in the file.

The expiry date and the owner of the license are printed out in the message file of LS-DYNA. The name of the license file also includes the company name and the expiry date of the dummy.
We recommend storing the license file of dummy models in a central place as read only. Furthermore the name of the license include should be simple like for instance


With a symbolic link from the current license to this name it is possible to keep older input decks running without updating the input data of them.

For the work in a pre-processor, an additional file is delivered:


This work file includes the same input as the encrypted license file. The only difference is the scaling of the load curves in the work file. The load curves are scaled randomly in a wrong range and they are much too soft to be used for a LS_DYNA simulation. But the file can be used to observe the quality and course of the material curves.

A LS-DYNA simulation in use of the work file will give wrong results and is very unstable. So if you observe dummy model crashes without appreciable load you should check if you included the load-curves-work file instead of the license file.
