# reset imt values of truncated mesh
|
||
|
|
|
||
|
|
Source imt values are the truncated imt values minus the node values that need to be reset.
|
||
|
|
|
||
|
|
This example removes materials greater than MAX_MAT.
|
||
|
|
The removal can leave behind node values that need to be reset.
|
||
|
|
We do not want to remove the nodes as we want to keep these cells.
|
||
|
|
|
||
|
|
Main command file with the truncation calls:
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
# truncate top of mesh, remove materials gt 8
|
||
|
|
|
||
|
|
define CMO cmotet
|
||
|
|
define MAX_MAT 8
