Hello!

I currently have ANSYS installed on my PC and have it linked to a teaching license through my university. I am attempting to do some MHD simulations, but when I go to add the MHD module through /define/models/addon-module, I get the error "Invalid Command [Addon-Module]"

I have included a screenshot for reference

Any guidance would be greatly appreciated

Can you load a mesh in and try again? Are you running 2d, 2ddp, 3d or 3ddp?

Adding a model to the environment fixed the issue. Sorry about that, should have been obvious.

For posterities sake, I was running 3d

Thanks Gage. It's only obvious once you've tried it - which I did too as it could have been something else. 

As an aside. Unless you've low on RAM it's generally a good idea to run double precision. It's something that was previously only recommended in certain scenarios but given the power of modern hardware there's very little reason not to now.
