I am trying to simulate a closed loop cooling system using simulink but facing this error continously.
If anyone can help me with this would be of great help?
I have uploded the file,if anyone can please run it and share the trouble shooting measures willbe of greta help.
I ahve uploded the mat variable file for initialization parameters of the model


I couldn't able to open the model. Because you designed in Simulink 2017a, So can you please upload 2016b simulink model or below version.

Hi Adit,
I could see an algebraic loop formed in your model by the signal coming to Total_pressure_BP input of Pump 1 subsystem. This is actually causing the issue. Try adding a Unit Delay block to the signal coming to Total_pressure_BP block.
For more information about identification and removal of algebraic loops have a look at these links:
Also in order to solve algebraic loops in models containing continuous blocks you could go through this link:
Hope it helps!
