Creating a profile using a mathematical function f(x,y)

Im trying to find a way in simulink so it can let me create a specific profile of a pressure and flow using a function directly and i was wondering if there's a way to do that ?

Thanks.

Hi,

As per my understanding, you can create a specific profile of pressure and flow using the "MATLAB Function" block in Simulink. You can follow the below steps:

• Double-click the "MATLAB Function" block to open the editor.
• Enter the code to define a pressure profile as a function of time (refer to the example function below:)

% Example Function (change as per requirements)

function pressure = pressureProfile(time)

% Example to generate a sinusoidal pressure profile

amplitude = 100; % Pressure amplitude in Pascals

frequency = 0.1; % Frequency in Hz

pressure = amplitude * sin(2 * pi * frequency * time); % Sinusoidal formula

end

• Drag another "MATLAB Function" block into your model for the flow profile.
• Double-click the new "MATLAB Function" block to edit and enter the code to define the flow profile as a function of time (refer to the example function below:)

% Example Function (change as per requirements)

function flow = flowProfile(time)

% Example to generate a linear flow profile

slope = 10; % Flow increase rate (units per second)

flow = slope * time; % Linear formula

end

• Add "Clock Block" and "Scope Block" to the input and output respectively.

Refer to the example design image below. You can make changes to the system as per your requirements.

For more information on the "MATLAB Function Block" refer to the below documentation:
