Running a biomechanics problem in serial batch mode
Contents
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 here and save it also to the <Continuity>/pcty folder
Linux / Mac
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
- 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 &
- 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
To run a job in serial on Windows7, go to Start Menu and type cmd. Click on cmd.exe to open a command window.
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.
