This is the public repository for the code sensBVP. Its use is in calculating sensitivity coefficients of ignition delay time to rate coefficients. In sensBVP, this is carried out by transforming the initial value problem to a boundary value problem, reducing the time to calculate the sensitivity coefficients by at least an order of magnitude.

In order to install sensBVP, modify the various paths in the Makefile. Make sure that SUNDIALS (v3.1.1 or higher), Cantera (2.3 or higher), and GSL are installed. Run make all, followed by make install in the source directory.

After installing, the executable sensBVP can be executed as follows:

residue tolerance> -T <initial temperature in K> -P <initial pressure in
atm> -m <mechanism file (cti or xml)> -c <mole fraction composition> -t
<integration time> -s <enable sensitivity analysis>

Execute sensBVP -h for all available options.

Try the cases in the examples directory.
