`DMIG`	(Optional) Flag indicating that the above variability values are applied to the specified `DMIG`s below.

MONCARL is only supported for Modal Frequency Response Analysis. Also, only 1 Modal Frequency response subcase can be defined for MONCARL.
The optional DMIG continuation line can be used to specify variability parameters for DMIG matrices which are defined as a LABEL-based SET Bulk Data Entry, such as:
```
SET,<SID1>,LABEL 
+,<DMIG1>,…,<DMIG2> 
```
The labels DMIGi can reference are:
1. DMIG matrices referenced by K2GG, M2GG, B2GG, K42GG entries.
2. H3D Superelement referenced by ASSIGN entries.
3. IDs of root internal superelements.
Multiple MONCARL entries with the same ID can be used to specify different variabilities to individual superelement matrices, and the DMIG continuation line can be omitted from at the most one MONCARL entry. If the DMIG line is omitted, then the specified variabilities will be applied to the residual structure (that is, each of the structural matrices excluding the DMIG matrices with separately defined variabilities).
