Fixes a
TypeErrorinThermoAdd.compute()when running with NumPy 2.x and OpenMDAO 3.42+.OpenMDAO 3.42.0 changed scalar inputs to be stored as
(1,)arrays rather than scalars. NumPy 2.0 removed implicit scalar conversion on 1-element arrays, soW_other_out[self.idx_compo] += W_other_mixfails because it tries to broadcast a(1,)array into a 0-d indexed slot.Fix: changed to
W_other_mix.item()to extract a proper Python scalar before the in-place add.Closes #116
