Warning: The model contains alias variables with redundant start and/or conflicting nominal values. It is recommended to resolve the conflicts, because otherwise the system could be hard to solve. To print the conflicting alias sets and the chosen candidates please use -d=aliasConflicts.
Warning: After manipulating the system with postOptModule wrapFunctionCalls the system is unbalanced. This indicates that the original system is singular. You can use -d=dumpCSE and -d=dumpCSE_verbose for more information.
Error: Too few equations, under-determined system. The model has 38 equation(s) and 40 variable(s).
