.dens file

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
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.
