CAEBAT in ICE

Revision as of 20:38, 3 February 2015 by Paul.roubekas.org (Talk | contribs) (→‎Running a Simulation with CAEBAT)

This page describes the structure and usage of CAEBAT, building instructions, how to run an example, and how it is related to ICE.

Introduction to CAEBAT

Computer-Aided Engineering for Electric Drive Vehicle Batteries (CAEBAT) is an open-architecture framework that integrates multi-physics and multi-scale battery models. After experimental validation, these simulations can be used for research, design, and manufacturing.

OASFramework

The OAS modeling framework integrates all the physics necessary for development of realistic and predictive battery performance and safety models. This framework uses a Python scripting language, and controls the battery state through component and state adapters.

The component adapters interact with the components by preparing the necessary inputs to run the components and by scheduling the component runs. The state adapters interact with the battery state file by updating all the necessary information about the battery state and the methods for coupling the components. The Battery state file is the core for passing data between components.

VIBE

VIBE expands to Virtual Integrated Battery Environment. The OAS framework, along with physics and support components and the adapters constitute the VIBE. The current components are electrochemistry, thermal, electrical, and cost model.

Other

The data for CAEBAT is in a tar.gz file available upon request.

The Battery Markup Language (Battery ML) provides standardized format for the definition of all the necessary information.

The BatteryML Schema controls the structure of the output, and it uses a relational data model to stay flexible and avoid data duplication.

CAEBAT in ICE

We plan to integrate CAEBAT into ICE as a plugin so we have a tool for simulating battery codes. ICE will simply use its current tools to run CAEBAT, behind the scenes. These are a compiled effort based on the meeting of 3/21/2013. We will design CAEBAT into three different pieces:

Model

There are multiple pieces to this particular module and will probably be the most complex. The CAEBAT program will require 3 types of input files in varying degrees of format and complexity:

  • The workstation.config. This will probably be pre-generated under the hood by ICE or another script and not be visible in the model builder.
  • The Chartran.config file. This is a configuration setup file for the simulation. This will be pre-generated with ICE's XML format for creating the model, and the input model will be generated in the listed format (a combination of key/value pairs with bracketing). Part of the k/v pair parsing is in NiCE, but will need to investigate K/V parsing for tables and MasterDetailsPairs.
  • The "model" BatML.file. The schema will be provided by the CAEBAT Folks where we will investigate a way to generically handle the schema file in order to produce the GUI layout in the model, and then transform the values inputted into the schema enforced xml file.

Launcher

The basic launcher in development will suffice, but will investigate looking into adding Entries into the JobLauncher to handle multiple input files.

Analysis ("Pretty Pictures")

AUTOCAD or other visualization tools to show the results of the simulation.

The standing basis for the model will be CAEBAT CASE 4 model.

Building CAEBAT

OASFramework

To create the OASFramework :

  • Create a directory CAEBAT and cd to that directory
  • Check out the source code from the repository using the following command:

svn checkout http://svn.code.sf.net/p/ipsframework/code/trunk OASFramework

  • To build the library, use the following terminal commands:

cd OASFramework mkdir build cd build ccmake ..

  • Press c to configure the build, then e to exit
  • Edit the key CMAKE_INSTALL_PREFIX to enter the bin installation directory /PATH/TO/OASFramework/install
  • Press c to reconfigure the build
  • Enter g to generate and exit from ccmake
  • make
  • make install

VIBE

  • Pre-install HDF5 and 32bit CGNS

For CGNS: in ccmake enable Fortran, HDF5 and tests. Also enable the tools if you wish to query the output.

If you want to perform optimization or parameter sweep, you also need to install DAKOTA (Design Analysis Kit for Optimization and Terascale Applications).

  • Untar the VIBE compressed file into the CAEBAT directory.

tar xzvf VIBE.tar.gz cd VIBE/trunk/components/config/ ln -sf makeconfig.gnu makeconfig.local cd ../ make

Configure the installation location to /usr/bin/install and remember not to end with a "/" make install (this will install everything in the bin directory under components)


DATA

Untar the DATA directory (tar xzvf CAEBAT-DATA.tar.gz) into the /CAEBAT directory.

Running a Simulation with CAEBAT

In order to run this, make a new directory in CAEBAT called RunExample. When going through these steps remember not to have "/" on the end, and that "Library" must be spelled correctly. Create the following directories in RunExample:

  • Data
  • Results
  • Physics

Move the following configuration files into RunExample:

  • thermal_chartran_cell_twoway.conf
  • workstation.conf

Move the following data files into RunExample/Data/dualfoil/

  • li-ion-ebar.in
  • dualfoil5.in

Configure the workstation.conf

  • Change PHYS_BIN_ROOT = /RunExample/Physics
  • Change DATA_ROOT = /RunExample/Data

Next, Configure the thermal_chartran_cell_twoway.conf

  • Change CAEBAT_ROOT = /CAEBAT/VIBE/trunk/components
  • Change SIM_ROOT = /RunExample/Results

Next, do sourcing to use the cgns library, by using the following commands:

  • vi ~/.bash_profile

Create a new Library by typing the following below your current library:

  • LD_LIBRARY_PATH=/opt/cgns-3.1.3-i686_gcc-4.4.6/lib:$LD_LIBRARY_PATH

Then you must restart the bash profile for this change to take effect by:

  • . ~/.bash_profile

The Battery Markup Language (Battery ML) provides standardized format for the definition of all the necessary information.

The BatteryML Schema controls the structure of the output, and it uses a relational data model to stay flexible and avoid data duplication. CAEBAT in NiCE

We plan to integrate CAEBAT into NiCE as a plugin so we have a tool for simulating battery codes. NiCE will simply use its current tools to run CAEBAT, behind the scenes. These are a compiled effort based on the meeting of 3/21/2013. We will design CAEBAT into three different pieces: 

   Model
   Launcher
   Analysis (tentative)

Model

There are multiple pieces to this particular module and will probably be the most complex. The CAEBAT program will require 3 types of input files in varying degrees of format and complexity: 

   The workstation.config. This will probably be pre-generated under the hood by NiCE or another script and not be visible in the model builder.
   The Chartran.config file. This is a configuration setup file for the simulation. This will be pre-generated with NiCE's XML format for creating the model, and the input model will be generated in the listed format (a combination of key/value pairs with bracketing). Part of the k/v pair parsing is in NiCE, but will need to investigate K/V parsing for tables and MasterDetailsPairs.
   The "model" BatML.file. The schema will be provided by the CAEBAT Folks where we will investigate a way to generically handle the schema file in order to produce the GUI layout in the model, and then transform the values inputted into the schema enforced xml file.

Launcher

The basic launcher in development will suffice, but will investigate looking into adding Entries into the JobLauncher to handle multiple input files. Analysis ("Pretty Pictures")

AUTOCAD or other visualization tools to show the results of the simulation.

The standing basis for the model will be CAEBAT CASE 4 model. Building CAEBAT OASFramework

To create the OASFramework :

  • Create a directory CAEBAT and cd to that directory
  • Check out the source code from the repository using the following command:

svn checkout http://svn.code.sf.net/p/ipsframework/code/trunk OASFramework

  • To build the library, use the following terminal commands:

cd OASFramework mkdir build cd build ccmake .. 

   Press c to configure the build, then e to exit
   Edit the key CMAKE_INSTALL_PREFIX to enter the bin installation directory /PATH/TO/OASFramework/install
   Press c to reconfigure the build

   Enter g to generate and exit from ccmake

   make
   make install

VIBE

  • Pre-install HDF5 and 32bit CGNS

For CGNS: in ccmake enable Fortran, HDF5 and tests. Also enable the tools if you wish to query the output.

If you want to perform optimization or parameter sweep, you also need to install DAKOTA (Design Analysis Kit for Optimization and Terascale Applications).

  • Untar the VIBE compressed file into the CAEBAT directory.

tar xzvf VIBE.tar.gz cd VIBE/trunk/components/config/ ln -sf makeconfig.gnu makeconfig.local cd ../ make 

   Configure the installation location to /usr/bin/install and remember not to end with a "/"
   make install (this will install everything in the bin directory under components)

DATA 

   Untar the DATA directory (tar xzvf CAEBAT-DATA.tar.gz) into the /CAEBAT directory.

Running a Simulation with CAEBAT

In order to run this, make a new directory in CAEBAT called RunExample. When going through these steps remember not to have "/" on the end, and that "Library" must be spelled correctly. Create the following directories in RunExample: 

   Data
   Results
   Physics

Move the following configuration files into RunExample:

thermal_chartran_cell_twoway.conf workstation.conf

Move the following data files into RunExample/Data/dualfoil/

li-ion-ebar.in dualfoil5.in

Configure the workstation.conf 

   Change PHYS_BIN_ROOT = /RunExample/Physics
   Change DATA_ROOT = /RunExample/Data

Next, Configure the thermal_chartran_cell_twoway.conf 

   Change CAEBAT_ROOT = /CAEBAT/VIBE/trunk/components
   Change SIM_ROOT = /RunExample/Results

Next, do sourcing to use the cgns library, by using the following commands:

vi ~/.bash_profile

Create a new Library by typing the following below your current library:

LD_LIBRARY_PATH=/opt/cgns-3.1.3-i686_gcc-4.4.6/lib:$LD_LIBRARY_PATH

Then you must restart the bash profile for this change to take effect by:

. ~/.bash_profile

Check that this library assignment worked by using:

  • echo $LD_LIBRARY_PATH

Every time the terminal is closed, the . ~/.bash_profile must be run to reassign this library. Now, to actually run the example use the following command while in /RunExample:

  • /CAEBAT/OASFramework/install/bin/ips.py --simulation=thermal_chartran_cell_twoway.conf --log=temp.log --platform=workstation.conf -a
