It is possible to run multiple times a simulation in Simulink in the same timestep?

Hello,

I have a model in Simulink and I which have input data that changes with time. It's a pump station with 3 machines, and depending on the flow (demand) may work one, two or three pumps.

In the code, I have the rules for 1 pump which is no problem. But for the cases when I can work with two or three pumps I also want to try with one, two or three pumps, and compare the output and choose the best based in a criteria.

(Hope I explained myself)

Thank you all in advance.

switch p  
    case '2p' %2 installed pumps
            if      Qd < Qmint %Case 1
                    b = 1
            elseif  (Qmint <= Qd) && (Qd< 2*Qmint)   %Case 2
                    b = 2 
            elseif  (2*Qmint <= Qd) && (Qd< Qmaxt)   %Case 3
                    b = 3       
            elseif  (Qmaxt <= Qd) && (Qd< 2*Qmaxt)   %Case 4
                    b = 4 
            elseif  (2*Qmaxt<= Qd)  %Case 5
                    b = 5
            end
    switch b
        case 1
            nf = 0 
            Qt = 0 % 0 pumps
            
        case 2
            nf = 1 
            Qt = Qd %1 pumps
            
        case 3
            nf = 2
            Qt= Qd/nf %1 or 2 pumps (In this case I want to try with 1 and 2 pumps and choose the best)
            
        case 4
            nf = 2
            Qt = Qd/nf %1 or 2, might work the PRV (Also in this case I want to try with 1 and 2)
                
        case 5
            nf = 2
            Qt = Qmaxt % 2 pumps + PRV

Hello Melvin, Im not sure I understand what you wish to do from the title of your question.

However, from the description provided, I think you can use Variant Subsystem block. The Variant Subsystem block can include three choices (design models), i.e, a model that has 1pump, other with 2pumps, and another with 3pumps. You can then set a conditions according to your usage (use a parameter that implies which works best and use it in your condition statement ). Variant Systems lets you choose a particular block design based on the criteria you set. So you will be able to choose between the three different pump models created by you. Hope this helps.

Refer to the below documentation to understand better :
