== Running a biomechanics problem in serial batch mode ==
[[TableOfContents(3)]]

=== Description ===
 * In this example we retrieve a complete dog model from the library, save it to disk, and solve the problem in serial batch mode using a script. It contains a normal biventricular dog model coupled to a closed-loop circulation. The script creates a folder '''dog_normal''' in your <Continuity>/pcty folder and will write into it nodal solutions and files with stress and strain components. You need to run your computer as an Administrator.
=== Start Continuity ===
 * Launch the Continuity 6.4 Client
=== Load Dog Model From Library ===
 * File→Library→Search...
 * Find the model named '''dog_normal_holzapfelmod_hillmod'''
 * Right click on the model and select '''Load'''
 * Select '''Reset (without save) then proceed'''; the '''''__second __'''''option.
=== Save the Model ===
 * File→Save→Save model as...
 * Go to the <Continuity>/pcty folder and save the model as '''dog_normal_holzapfelmod_hillmod.cont6'''
=== Obtain the Script and Execute it ===
 * Get the script [attachment:dog_normal.py here] and save it also to the <Continuity>/pcty folder
=== Linux / Mac ===
 1. To run a job in serial on Linux or Mac, open a Terminal window and type this in the <Continuity>/pcty folder:
  . {{{
./continuity --full --no-threads --batch dog_normal.py     }}}
 1. If the job needs to be able to run even after you close your terminal window, type this:
  . {{{
nohup ./continuity --full --no-threads --batch dog_normal.py > contoutput.txt &     }}}
 1. To check the progress of your job, use the command "tail -f" like this:
  . {{{
tail -f contoutput.txt     }}}
  And Ctl-C when you are done reading the output.
=== Windows ===
 1. To run a job in serial on Windows7, go to '''Start Menu''' and type '''cmd'''. Click on '''cmd.exe''' to open a command window.
 1. Then go to the <Continuity>/pcty folder and type:
  . {{{
ContinuityClient.bat --full --no-threads --batch dog_normal.py     }}}
=== End of Simulation ===
 * This simulation will solve for a full cardiac cycle with a basic cycle length of 750 ms in 750 steps. In serial mode that will take hours, so you may want to quit the simulation prematurely. Have a look at the solution and stress and strain files that are written into <Continuity>/pcty/dog_normal.
