Technical Support

If you have a problem using GAMS please don't hesitate to contact us.

There are several reasons why you may want some help:

  • GAMS has problems with your hardware or operating system
  • You think GAMS does not do what it should do
  • The solver has problems solving your model
  • You are stuck with a modeling or formulation problem

Just send us an email or call one of the phone numbers below.

Worldwide Technical Support

Of course we cannot do all the modeling work for you (unless you hire us as a consultant) but we have lots of experience in using GAMS in both small and large, complex modeling situations in all kind of different application areas, ranging from economics to chemical engineering. Just talking to us for a few minutes may put you on the right track again. In case you think GAMS or the solver fails, please provide us with as much relevant information as possible about the problem, for details please consult this check list. Also feel free to visit our Support Wiki - maybe your issue has already been adressed.
