HI Alex, I think the technology has now been merged. I am cc’ing Joao to provide you with some details but I think there should also be something in the uer guide. Best, Spencer.

Hello Spencer, thanks for the quick response. I searched the 5.6.0 User Guide and didn't find anything. Perhaps I should have also mentioned that I was primarily concerned with the IncNavierStokesSolver, as Joao was referring to the CompressibleFlowSolver, if I remember correctly.

Hi Alex, We have merged that functionality into Nektar about a month ago and is available if you build the current master User-guide (sec 3.6.3 page 72) has some instruction on how to use it and you can also look at the following test “ChanFlow3D_infTurb.xml” located in “nektar++/solvers/IncNavierStokesSolver/Tests” Just note that since this is a test, we have restricted the number of eddies. You will need to remove/comment out the <TestCase> tag in the Forcing tag (I highlighted it below) for the real application. <FORCING> <FORCE TYPE="IncNSSyntheticTurbulence"> <ReynoldsStresses> ReyStresses </ReynoldsStresses> <CharLengthScales> LenScales </CharLengthScales> <BoxOfEddies> 1.0 0.0 1.5707963267948966 2.0 3.141592653589793 </BoxOfEddies> <Sigma> 0.7 </Sigma> <BulkVelocity> 1.0 </BulkVelocity> <TestCase> ChanFlow3D </TestCase> </FORCE> </FORCING> Cheers, Mohsen From: nektar-users-bounces@imperial.ac.uk <nektar-users-bounces@imperial.ac.uk> on behalf of Sherwin, Spencer J <s.sherwin@imperial.ac.uk> Date: Wednesday, 9 October 2024 at 12:31 To: Alexander Schukmann <alexander.schukmann@protonmail.com>, nektar-users <nektar-users@imperial.ac.uk>, Isler, Joao A <j.isler20@imperial.ac.uk> Subject: Re: [Nektar-users] Synthetic Eddy Method ⚠ External sender.
