The .dens file is an OptiStruct ASCII format results file.
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 options FORMAT and OUTPUT).

Description |
|
Density |
Density results from topology optimizations. Output is controlled by the I/O option DENSRES. |
The density file has the following format:
|
For each iteration, the following header is used: |
|||
|
|
iter |
Iteration |
Numel |
|
where: |
|||
|
|
iter |
is a keyword identifying that the next field is the iteration number. |
|
|
|
Iteration |
is the Iteration number. |
|
|
|
Numel |
is the total number of elements in entire model. |
|
|
|
|||
|
Within the iteration section, the following information is provided for each element: |
|||
|
|
EID |
Mat_dens |
|
|
where: |
|||
|
|
EID |
is the element identification number. |
|
|
|
Mat_dens |
is the element material density. Non-design elements are assigned a material density of 1.0. |
