Being able to remove equations from a model

Hello,

If I'm not mistaken, there is currently no way to remove equations from the equation settings. This has caused considerable confusion, as deactivating equations causes eigenvalues to repeat themselves for a mode analysis I'm trying to do. In that sense this is both a suggestion and bug report. I hope this can be resolved.

Thank you for the suggestion, functionality to remove physics modes should be available in the next update.
