Hi,Help please,when i try to run my Simulink model, i obtain this error:
Cannot solve algebraic loop involving 'Nussbaum/Switch' because it consists of blocks that cannot be assigned algebraic variables, i.e., blocks with discrete-valued outputs, blocks with non-double or complex outputs, Stateflow blocks, or nonvirtual subsystems

Do you have an output connect as an input (in a loop)? Perhaps you might want to avoid the algebraic loop in the first place so that Simulink doesn't have to solve it. Please see What are algebraic loops in Simulink and how do I solve them? and this blog post: http://blogs.mathworks.com/seth/2008/07/03/how-did-i-get-an-algebraic-loop-error-when-the-diagnostic-was-set-to-warning/
Also, this previously answered question has a lot of good tips: http://www.mathworks.com/matlabcentral/answers/34478-is-this-the-way-to-solve-algebraic-loops

Iman: Ideally, you should post this as a new question, but I'll try and answer it anyway. I think you need to "pre-allocate" sn1. Just add something like "sn1=0" before the if block.
