xStiff Usage

Follow the steps required to use the xStiff utility.

It is important to understand that xStiff is a completely separate utility and is run by itself (not within Abaqus). To invoke xStiff, the following steps are required:

1. Open the Simulation Composite Analysis 2015.1 Command Shell by clicking the desktop icon (or Start > Autodesk > Simulation Composite Analysis 2015.1 > Simulation Composite Analysis 2015.1 Command Shell).
2. Change the directory of the command prompt to the directory that contains the input file to be modified.

   >>cd < path of input file >

   Example:

   >>cd C:\Autodesk

   

3. Invoke xStiff.

   >>xstf /i < input filename >

   Note: Do not include the .inp extension.
   Example:

   >>xstf /i sampleJob

   

4. A new input file appended with _xs will be created in the directory where the original input file was located. This new input file will have all the extraneous stiffness parameters required to execute an Abaqus analysis using Simulation Composite Analysis materials.
