I think AfCmode
is not being set. Can you verify this from the OpenFAST inputs?
I would set it around here with
self.modeling_options['Level3']['ServoDyn']['AfCmode'] = 5
Sorry, I am not set up with XFoil or working on flap control much, so I might not be able to provide a lot of good support/testing for this.
@dzalkind, this fixed the problem!
I'd recommend committing the change you suggested, because I don't think example 07 will work properly without it.
Thanks so much!
As a quick follow-up:
You can also fix this problem by adding "AfCmode: 5" to the ServoDyn section of the example modeling_options.yaml
This will avoid having to make any changes to the general code if that's what is desired, but I like the idea of baking it into a conditional statement like @dzalkind suggested, since any flap control option will probably need it.
Thanks again for the help!
This issue has been open for a while, so I'll add a new issue that I ran into while working with this example.
In BAR_USC_flaps.yaml, under components/blade/aerodynamic_control/te_flaps, the span_start and span_end are very close to each other (0.7 and 0.71, respectively). When I was running examples comparing the different flap modes, I was getting no discernible difference in turbine response, despite the very different blade flap behavior (the plots of tip deflection and root bending moments were visually identical).
@Ben-Mertz figured out this was the cause of the apparent lack of turbine response, and has verified that increasing the amount of span occupied by the te flaps does produce a more noticeable response. Because this is an example, meant to demonstrate to a new user how to integrate te flaps into their model, it may be a good idea in a future commit to increase the initial span of the te flaps in the BAR_USC_flaps.yaml
PR #213 should help close this issue
Description
Develop Branch, example 07_te_flaps appears to be incapable of producing flap actuation as currently set up.
