# RESTARTW

I/O Options and Subcase Information Entry The RESTARTW entry can be used in the I/O Options section to define the control parameters for nonlinear restart.

## Format

RESTARTW = n, option, option2, path

## Example

RESTARTW = 1
RESTARTW = 5, NOCOV
RESTARTW = 5, NOCOV, D:\tmp
RESTARTW = 5, COVER, RMDX, D:\tmp


## Definitions

Argument Options Description
n Integer > 0

No default

Identifies the frequency of writing nonlinear restart analysis information files.

Restart analysis information files (*.rnl) are written after every n increment(s) and after the last increment for a nonlinear subcase. 1

option COVER, COVE2, NOCOV
COVER (Default)
Whenever a new restart analysis information file (*.rnl) is written, the previous restart analysis information file is removed, unless it was the last frame for a nonlinear subcase.
COVE2
Whenever a new restart analysis information file (*.rnl) is written, the previous restart analysis information file is removed, unless it was either of the last two frames for a nonlinear subcase.
NOCOV
Previous restart analysis information files are not removed.
option2 RMDX, Blank
RMDX

Activates enhanced Restart functionality where, in addition to the traditional *.rnl file, a new <filename>.rmdx file is output. The new .rmdx file contains the full model information and you can define only additional data (new subcases and so on) in the RESTARTR run. In this case, the traditional .rmd restart model file is not output.

Blank (Default)
The traditional Restart functionality is active and the .rmdx file is not output. The traditional .rmd restart model file is output; therefore, the subsequent RESTARTR run should contain the full model plus any changes that are required.
path <directory path>

Default = Scratch file directory

Path to the directory where restart files are to be written. 2
Note: This argument is only supported if RESTARTW is specified above and outside the subcase.
