# Discussion Forum

COMSOL provides the Discussion Forum for the benefit of our user community to share ideas with each other, and for open discussion on topics that are of interest to the COMSOL Multiphysics user base.

While COMSOL employees may occasionally participate in Discussion Forum discussions, their contributions to a specific topic or technical question may not be as comprehensive as a response to a support request handled through COMSOL's support process.

All of COMSOL's on-subscription customers are welcome to submit their questions via: www.comsol.com/support to be addressed individually by the COMSOL Technical Support Team.
