Hello everyone,

Do the different module like convectivity enhanced conductivity not present in the COMSOL 6.3 latest version?

I am currently working in the COMSOL version 6.3, I have 6.1 version in my other PC, I want to open my that file in old version. I am unable to change my version. Please help me.

If a licensing issue is the problem in upgrading Comsol 6.1, then I suggest you contact Comsol support. Maybe you can get an upgrade based on your existing Comsol 6.3 license. It won't hurt to ask them. :)
