[FLASH-USERS] Implementing Jet via

[Alex Robinson - UKRI STFC]

Hello flash users,
     I would have thought that this has already been done, however I would like to set up a simulation where a jet is injected by implementing a boundary condition for this.  I had thought that using ‘Wind Tunnel’ as a basis for this would be a good idea, and using the ‘GridBoundaryConditions/OneRow’ approach where I have my own Grid_applyBCEdge.F90 file in the simulation directory.  This compiles fine (setup line reads : ./setup Jet -auto -2d +cylindrical +ug -nxb=200 -nyb=200) .  However when I try to run this, the simulation aborts with the message : DRIVER_ABORT : unsupported boundary condition on Lower Face.  This is after I set the yl_boundary_type to be either ‘user’ or ‘user-defined’.  I have specified REQUIRES Grid/GridBoundaryConditions/OneRow in the config file.

This message implies that despite my Grid_applyBCEdge.F90 file being in the simulation directory that it hasn’t overridden the default method as no ‘user’ implementation appears in the standard file in the source.  However I can’t see what I haven’t done that has lead to the overriding not happening.  Any advice?

Thanks,
Alex
