Hi. i want to run attachmented files and plot frequency(W) against logaritmic of ratio of displacement 5 to 1(U5/U1). when i run attachmented files face warning message like this:
"Warning: Block diagram 'asuume' contains 5 algebraic loop(s). To see more details about the loops use the command Simulink.BlockDiagram.getAlgebraicLoops('asuume'),
or the command line Simulink debugger by typing "sldebug asuume" in the MATLAB command window. To eliminate this message, set the Algebraic loop option in the
Diagnostics page of the Simulation Parameters Dialog to "None"
> In data (line 18)
Found algebraic loop containing:
'asuume/ddUcell' (algebraic variable)
'asuume/dd THp' (algebraic variable)
Found algebraic loop containing:
'asuume/ddUcell1' (algebraic variable)
'asuume/dd THp1' (algebraic variable)
Found algebraic loop containing:
'asuume/ddUcell2' (algebraic variable)
'asuume/dd THp2' (algebraic variable)
Found algebraic loop containing:
'asuume/ddUcell3' (algebraic variable)
'asuume/dd THp3' (algebraic variable)
Found algebraic loop containing:
'asuume/ddUcell4' (algebraic variable)
'asuume/dd THp4' (algebraic variable)"
please help me that how i correct this code matlab attachment untile i extract curves above.
thank you

I disagree. Messages about algebraic loops indicate that you have not properly connected your blocks, and that SImulink has guessed about how to connect the blocks. You need to repair the model.

I think I know what you mean by "not properly connected" in this context, but that's not always the case. Sometimes algebraic loops are introduced intentionally, for example to solve a DAE. Not saying that's the best way to solve a DAE, but it's certainly an option.
Simuink doesn't guess about how to connect the blocks. It attempts to solve the algebraic loop as presented, unless the model is set to generate an error on an algebraic loop.
