Needed help in simulation

I would like to know any link or tutorial or topic that i have to or i can use to simulate 17 first order differential equations, ones output is actually given to the next block and this has been very confusing for me and I'm on a deadline to finish my project work in 3 days.

Desperate situation, i know but I would appreciate the help

Thanking you

Can you provide a small, simple example (maybe two or three equations) that illustrates the structure of the problem you wish to solve?

Hi @Akshay Chakrapani

Since you have the blocks, better show the block diagram for clarity.

Based on your description, probably there are 17 integrator blocks, where the output of an integrator goes into the input port of another integrator.

I will post few of the equations which gives a minimal model @Paul...i hope this can suffice

Thank you very much

[Akshay Chakrapani]

@Sam Chak I will soon post the picture of the simulink model, Do you want to see the connection in between blocks also?

[Benjamin Thompson]

Post the model file. This image is not good enough to see anything.

@Benjamin Thompson Hello! I have attached the file and the errors that I'm getting are too much for me to handle. Kindly please assist me

Hi Akshay,

You can refer to these resources to learn modelling differential algebraic equations in Simulink:

Model Differential Algebraic Equations - MATLAB & Simulink (mathworks.com)

Solving Differential Equations Using Simulink (uncw.edu)

Hope it helps!
