The .dens file is an OptiStruct ASCII format results file.
File Creation
This file is created when the OPTI, OS or BOTH formats are chosen and a topology optimization is performed. (See documentation for the I/O Option OUTPUT).
File Contents
| Result | Description |
|---|---|
| Density | Density results from
topology optimizations. Output is controlled by the I/O Option DENSRES. |
File Format
The density file has the following format:
For each iteration, the following header is used:
| iter | Iteration | Numel |
- Data
- Description
- iter
- Keyword identifying that the next field is the iteration number.
- Iteration
- Iteration number.
- Numel
- Total number of elements in entire model.
For each iteration, the following header is used:
| EID | Mat_dens |
- Data
- Description
- EID
- The element identification number.
- Mat_dens
- The element material density. Non-design elements are assigned a material density of 1.0.
