Question QC-002:
I get an error message from TRANSOR for I-DEAS that the number of element
groups exceeds 200. What is the problem?
Answer:
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.
Example:
|
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 500
This will set the maximum number of element groups to 500.
