I get an error message from TRANSOR for I-DEAS that the number of element groups exceeds 200. What is the problem?
During the translation of the I-DEAS model, the following rule is used for creating a new element group division.
- When looping over all the elements according to element label order, if the element type OR material type of the element is different from the previous element, a new element group division is created.
|Element Labels||Element Type||Material||Group Division|
|1 - 25||Shell||20||1|
|26 - 77||Shell||23||2|
|78 - 122||Shell||20||3|
|123 - 129||Beam||20||4|
|130 - 184||Shell||20||5|
In general, if the number of element groups exceeds 200, it may mean that the element label sequence is too fragmented. If that is the case, it is advisable to re-label the elements in I-DEAS such that elements of the same type and material are labeled in a contiguous manner.
In the above example, by re-labeling the elements such that all the shell elements with material 20 are contiguous, the number of element group divisions will be reduced from 5 to 3.
If the error message still occur after re-labeling the elements, you can increase the maximum number of element groups by using the TRANSOR option file. Create a file called "transor.opt" in the working directory with the following text in the file.
MAXA_EGROUP_DIVISION 500This will set the maximum number of element groups to 500.
