[[ICME 2013|< Back to ICME 2013 Course Overview]]

=Objectives=
* Run a multigrain crystal plasticity single finite element simulation.
* Calibrate macroscale BCJ Plasticity Internal State Variable (ISV) model
* Run 1 element finite element calculation.
* Validate Results.

=Preparations=
==Step 1==
* Follow the [[ICME 2013 HW3|guide from homework 3]] for a single grain crystal plasticity finite element simulation.
* Alter the inputs for 180 grains with random Euler angles.

==Step 2==
* Use the [[Code: DMG|MSU Plasticity-Damage (DMG)]] model calibration tool to fit a stress-strain curve from crystal plasticity as demonstrated in class.
* Save the parameters.

==Step 3==
* Visit the [[Macroscale]] page and collect the user material (UMAT) and ABAQUS input file for aluminum in tension (implicit).
* Save these files into a new working directory.

==Step 4==
* Alter the ABAQUS input file with the parameters calibrated to the DMG model.

=Running the Calculation=
==Step 1==
* Open permissions on files<pre>chmod 755*</pre>

==Step 2==
* Enter the following software setup command in a terminal:<pre>swsetup abaqus</pre>

==Step 3==
* Submit the abaqus job either locally or to Raptor using the following command:<pre>abaqus job=NAME_OF_INPUT user=NAME_OF_UMAT</pre>
* Do not include the file extension (.inp) in the "NAME_OF_INPUT".
