Question: VolturnUs example not working when setting potModMaster to 0

[maucollu]

Dear all,
I've followed all the instructions to install RAFT, and I am able to successfully run the example script in https://openraft.readthedocs.io/en/latest/starting.html using the VolturnUS-S.yaml default file.
Nonetheless, the setting for potModMaster is 1, i.e. "1=turns all potMod vars to False (no HAMS)", although some of the elements (center_column and outer_column are defined as "potMod : True".
When I change potModMaster to 0 (0=keeps all member potMod vars the same), I obtain the following error:
`Found mean offets with with surge = 0.02 m and pitch = 0.00 deg.

@maucollu, thanks for raising this issue. We still need to set up some proper tests for RAFT to catch things like this sooner. It sounds like something isn't working out with the call to HAMS.

@gbarter, would you have any insights on this error, or a suggestion of who would be well suited to look into it?

[gbarter]

I'm not immediately sure what the issue is. It reads like pyHAMS cannot find or open the windows executable that it currently ships with. Since it looks like pyHAMS is installed from the error message, this will indeed take some testing. I can try to take a look next week.

@mattEhall Perhaps a 'debug' toggle for the user to switch on which would provide a little more information?

e.g.

def run_hams(projectDir):
    '''call the HAMS_x64.exe program in the specified project directory'''
    # get absolute path to the local HAMS_x64.exe program
    hamsDir = osp.dirname(__file__)
    hamsExe = './bin/HAMS_x64.exe'
    hamsPath = osp.abspath(osp.join(hamsDir, hamsExe))
    if debugToggle is True:
        print(hamsDir)
        print(hamsExe)
        print(hamsPath)

to see if there is a path mix-up?

(or maybe save a .log file instead of just printing)

Hi all,

I have migrated pyHAMS to a more current build system (meson with ninja), which seems to be the way that SciPy and other major python numerical tools are migrating. I have also added a regression test in the CI that checks a cylinder run via pyHAMS against truth values in the upstream HAMS repo. This is run on Windows and Linux and is passing.

@maucollu - Please update to the latest pyHAMS and reinstall that package. If you continue to see the same error, then we know it is an issue with your system in particular.

Cheers,
Garrett
