Support Information
gModeler is a free product that I work on in in my free time. As such, no support is offered or implied. However, I will try my best to keep the manual, FAQs and known issues section of this site current and up to date.

That said, I appreciate feedback. If you find a bug, notice a problem with the online manual, have an idea or just want to tell me what you think of gModeler, there are a few ways to contact me:
  • Using the Send Feedback feature in the gModeler menu of the app.
  • Through my website contact form on
  • Sending an email to (remove the X's around the @ symbol).
