# .mapdsp file

The .mapdsp file is an OptiStruct ASCII format results file.

## File Creation

This file is created when PARAM, LCLGRDST, <GRID_SETID> is defined in the local model during a submodeling job, where GRID_SETID is a set of nodes defined in the local model.

## File Contents

This file contains the mapping information of each local node to the global nodes, for all local nodes in the grid set.

## File Format

The .mapdsp file contains the subcase information in the header.
 Subcase ID
It is followed by the mapping information for each local node.
 N_G1 Global nodes used in mapping for local node L1_ID G1_ID G2_ID etc. GN i_ID etc. GN G_ID
Where,
• Subcase_ID : Subcase ID of the local model
• N_Gi : Number of global nodes mapped to the ith local node
• Li_ID : ID of the local node
• GN i_ID : ID of the ith global node

## Example

An example output in the .mapdsp file is as follows:
Subcase ID             2005
3 Global nodes used in mapping for local node            61040
1176      1177      1197
3 Global nodes used in mapping for local node            61041
1176      1177      1197
3 Global nodes used in mapping for local node            61042
1176      1177      1197
4 Global nodes used in mapping for local node            61043
1156      1157      1177      1178
