ODE solver in DWSIM

[The One]

Hi,
I am trying to model a batch reactor in DWSIM using python. I was not able to understand the syntax for ode solver given in example code by Daniel. Can someone just write the code on how to solve ODE with all appropriate import statements? Thank you

Thanks for replying. What modules should be imported for the above code to run?
I am getting error "name "OdeFunction" not defined". I am working on version 5.7, update 12.

import clr
clr.AddReference('DWSIM.MathOps.DotNumerics')

from DotNumerics import *

I am still getting the same error: "name "OdeFunction" not defined".

Would be gr8 if u could once see the file.

Try

from DotNumerics.ODE import *

In RungeKutta45 method, what does exception :larger nmax needed means?

[Mario Cilento]

but can we use other python libraries to extend calculation capabilities?

i mean with scipy one can use odesolver, with numpy one can manage better arrys ... even to elaborate a linear interpolation i am writing by myself the interpolation with python lists (it is time consuming).
