I am developing a set of ODEs and constraints to be solved using the dsolve(MoLSYS, numeric, method=rosenbrock_dae).  The smallest system that I can set up to test my program is 3500 functions X 3500 equations.  Unfortunately, dsolve doesn't return any result or error of any kind, even after an hour.  Can anyone here please tell me the practical limit on the number of functions/equations that the DAE solver can handle?

Thank you,
