COMSOL 5.1 Update 3 Released September 7, 2015

This update corrects a few bugs and stability issues in Version 5.1 of COMSOL

Multiphysics, COMSOL Server, and COMSOL Client. It also makes it possible to run

COMSOL 5.1 on Windows® 10.

If you are already running Windows 10 or have updated to Windows 10, you must

apply the COMSOL 5.1 Hotfix for Windows® 10 in addition to applying this update. If you

make a complete installation of COMSOL 5.1 using the latest download (includes the

contents of Update 3), the Hotfix is not needed. This applies both if you already have

installed Windows 10 or plan to update later on.

The update is cumulative; that is, it applies to Version 5.1, Version 5.1 Update 1, and

Version 5.1 Update 2, and it includes all updates from the previous Update 1 and

Update 2.
