From 4b6ebf95ba14a348e8e7347499cb7cba1d09109b Mon Sep 17 00:00:00 2001 From: Carl Recine Date: Thu, 12 Sep 2024 16:37:09 -0700 Subject: [PATCH 01/70] Added calculation for unset form factors Note: this behavior is different from GASP the form factors will always be calculated, but if they are present in the input deck the variable overriding will replace the calculated value with the one constant from the input deck. In gasp, these variables would only be calculated if the value wasn't set or if it was set to a value less than zero --- aviary/interface/methods_for_level2.py | 2 +- aviary/mission/gasp_based/ode/params.py | 4 - .../aerodynamics/aerodynamics_builder.py | 3 - .../gasp_based/gasp_aero_coeffs.py | 115 ++++++++++++++++++ .../gasp_based/premission_aero.py | 6 + .../gasp_based/test/test_gasp_aero_coeffs.py | 44 +++++++ 6 files changed, 166 insertions(+), 8 deletions(-) create mode 100644 aviary/subsystems/aerodynamics/gasp_based/gasp_aero_coeffs.py create mode 100644 aviary/subsystems/aerodynamics/gasp_based/test/test_gasp_aero_coeffs.py diff --git a/aviary/interface/methods_for_level2.py b/aviary/interface/methods_for_level2.py index cee35bbd9..43208c42b 100644 --- a/aviary/interface/methods_for_level2.py +++ b/aviary/interface/methods_for_level2.py @@ -1935,7 +1935,7 @@ def _add_bus_variables_and_connect(self): def setup(self, **kwargs): """ - Lightly wrappd setup() method for the problem. + Lightly wrapped setup() method for the problem.
