Parameter Equal to Total Length
Parameter Equal to Total Length
This is optional. If defined it gives a parameter name (as defined by the *PARAMETER keyword) that will be updated with the total length of the as-meshed belt each time it is generated. This can be referred to elsewhere, typically in *ELEMENT_SEATBELT_SENSOR , to update attributes in accordance with the revised belt length. See Parameter to contain the total seatbelt length for more details.
Add _Sn parameter for each segment
As an extension to the above if this option is selected each segment of the belt will have its length assigned to a separate parameter, which can be used in any context.
To save having to define multiple names these parameters are given the name of the total length one above with "_s1", "_s2", etc added for segments #1, #2, etc. For example:
| Nomenclature of per-segment parameters if parameter for total length is called BLEN | |
| Segment 1 | BLEN_S1 |
| Segment 2 | BLEN_S2 |
| ... etc for all belt segments. | |
Parameter names may not exceed 9 characters in normal Ansys LS-DYNA format, or 19 characters in long format. Therefore the name of the total length parameter will be truncated if necessary when adding " _S n " suffices in order to stay within these limits. For example if the total length parameter is " beltlen " then the parameter for segment #1 will be called " beltle_s1 " in normal format.
