M00 File Description

 Previous topic Next topic JavaScript is required for expanding text JavaScript is required for the print function  

The M00 file contains the description of Macro-objects, which do not exist in RADIOSS Input. It is useful for HyperCrash. This description refers to objects contained in the D00 Block Format file; a M00 file has no meaning without its associated D00; therefore, if the D00 file is named ROOTNAMED00, then the M00 will be named ROOTNAMEM00.

When some characters or fields appear between parenthesis ( ), then either they are not mandatory or the two forms may appear:

Example 1:

/TREE/ASSEMBLY/assembly_id(/assembly_title)

In the M00 file you may find:

/TREE/ASSEMBLY/1   or   /TREE/ASSEMBLY/2/assembly_title

Example 2:

(UN)CREATED

In the M00 file you may encounter either the word UNCREATED or CREATED.

Connections describe local RADIOSS modeling for entities such as spotwelds. Two notions exist: the elementary connection, which is the description of one spotweld linking a set of parts, and the logical connection, which is a set of elementary connection linking a set of part. This distinction exists for SPOTWELD, BOLT, HEMMING, and WELDLINE.
