fluid_flow.i example problem

[Gavin Ridley]

Hi all,

I have been trying to run the moltres/problems/fluid_flow.i. I get the error:

*** ERROR ***
A 'INSMomentumNoBCBC' is not a registered object.
We loaded objects from the following libraries and still couldn't find your object:
(NONE)

So, here is my problem. I have:

[gavin][~/projects/moltres]> printenv | grep MOOSE_LIBR
MOOSE_LIBRARY_PATH=/home/gavin/projects/moose/modules/navier_stokes/lib

Is there some kind of MultiApp option missing from the input file?

Ah, it makes me so happy to have user(s) :-) So the issue is that we're not building Moltres currently with the Navier Stokes module. I did this because while assuming a constant velocity for temperature and precursor advection, we didn't actually need it and it reduced compile time. But if we have somebody interested, then I'll load it in!

You can pull from arfc/moltres `devel` and then run `make` again, and then hopefully you don't see that error again.

Ah, there's another issue here that I'll fix shortly...stay tuned

Ok Gavin, that input file should run successfully now. It does on my machine. There have been some API changes to the navier stokes module that had to be addressed in a number of input files. There's a good chance that there are other changes lurking around there that haven't been caught. Only our tested input files are protected against MOOSE API changes. Almost certainly more uniform test coverage of kernels and boundary conditions that are used in input files throughout the Moltres repo should be put in place. (Or input files that haven't been used in a long time should be deleted...either way percent coverage should be higher)
