ANSYS File: PREP7 and SOLU Commands
Description
The PREP7 and SOLU commands set the ANSYS processor states for specifying pre-processor and solver related data. The PREP7 section contains the model data, including coordinate systems, node coordinates, element types, element geometry, material properties, element connections, components and constraint equations. The SOLU section contains load case dependent data, including constraints, nodal loads, surface loads, body loads, inertia loads and load step options. Many of the commands valid in SOLU are also valid in PREP7. The PREP7 and SOLU processor states begin with /PREP7 and /SOLU respectively and end with FINISH. Strand7 imports and exports most of the common PREP7 and SOLU commands.

Exporting
Strand7 writes all data within the PREP7 section with the exception of data valid only in the SOLU processor state. The PREP7 and SOLU processor states are supported by the ANSYS text file formats as follows:
| Format | PREP7 | SOLU |
|
Batch (1 file) |
Supported |
Supported |
|
Batch (3 file) |
Supported |
Supported |
|
Blocked CDB |
Supported |
Not Supported |
|
Unblocked CDB |
Supported |
Not Supported |
Strand7 will write data supported by the PREP7 processor state only if one of the CDB formats is selected.
