Hi, I would be grateful if anyone could help find inconsistency in a system of equations I have been solving. I can easily solve the system (that I have called ‘EQs’) when I set the parameter ‘tau\_l’ equal to .06, but for a different value, it will not solve. The same thing happens whenever I change the value of some other parameters like ‘l3’. Regards

Hi, I'm trying to solve without success numerically the following system of 15 nonlinear equations. Could anyone help, please? Thanks
