HI Alexander, Not sure if anyone has got back to you. I do not think we have a working DG inc Navier-Stokes yet since using DG does lead to a slightly different polynomial space. However I believe Boyang (cc’ed) has been looking into this. Cheers, Spencer.

Hello everyone, I have a quick question regarding the user guide entry for the ICNS solver. The table of possible values for the EqType tag under 11.3.2 in the 5.5.0 user guide does not list "DG" as a projection for the unsteady NS equations (only CG and CG-DG, i.e. mixed projection). However, under 11.3.3 under "Driver" it says DG for the Standard driver. I am a little bit confused as to whether the ICNS solver can be used with DG projection or not and would appreciate some clarification. All the best and thanks a lot!
