- Python3
- Don't support any problems from python2 environment
- numpy library required.
pip install numpy on bash.
Please read the sample system file
nutrient_system_ksp.txt
Each terms in any line has an indicator.
k is for reaction rate component
& is for the name of a component
* is for each term for differential equation expression
$ is for initial molar density
@ is for molecular weight
ion ends with #
cation absorption equation starts with =
cation absorption equation has Q, B, M, N.
Q is Da/SF^1.5
N is the number of electron an cation lost.
The ions inside the plant has indicator 'p' in front of names.
Differential equations which contains reaction rate constant k should follow after k indicators.
To hanlde a component which appears on differnt differential equations; you don't have to combine those equations into one line. This model automatically does it.
You may just import the module on you source code.
import system_simulator as ss
network = ss.Network(filename)
network.synchronous_update()
network.converge()
network.show_result()
network.write_result(filename)
network.export_cytoscape
It does not work when cation absorption model is applied.

result_dir : Directory where the result .csv files are stored.
network_dir : Directory where the network files used for the simulation are stored.
normalization : A boolean value. If True, it normalizes the data.
X -= np.min(X) X /= np.max(X)
Y = np.log10(Y)
Y -= np.min(y)
Y /= np.max(Y)
ISE_observable : A boolean value. If false, all components are processed. If True, only the components below are processed as X values.
(NH4+, NO3-, K+, Ca++, pH, TDS_of_nutrient_solution)
