Hi Emre,

As the error suggests, your model contains an algebraic loop and before generating code for the same you need to eliminate that. You can refer to the following documentation to see how that can be done:

As for the ‘ashow’ command, it helps to identify and highlight algebraic loops in simulation debugging session. Here is a link you can go through to know more about the command:

Hope it helps.
