[FLASH-USERS] Implementing Jet via

[Ryan Farber]

Hi Alex,

I agree that the WindTunnel's Grid_applyBCEdge is a good starting point.
In Grid_applyBCEdge, the user boundary condition is triggered if bcType ==
USER_DEFINED where USER_DEFINED is #defined to be -38 in my constants.h

Grid_init grabs xl_boundary_type from flash.par and maps that string to an
integer. So you could check to make sure that initial part is proceeding
correctly (i.e., if you print out gr_domainBC(LOW,:) do you get a value
matching USER_DEFINED in your constants.h?
If so, you can then forward trace gr_domainBC until you get to where your
abort is that Ernesto pointed out (or backtrace from there).

In any case, I would guess that using +cylindrical geometry is the issue.
Do you get the abort message without that (i.e., for cartesian)?

Also, what version of FLASH are you using?

Best,
--------
Ryan
