To specify the dynamic blade element momentum (DBEM) theory options.
Refer to AeroDyn Overview for further information.
Two lines of data, defining dynamic blade element momentum theory parameters as follows:
DBEMT_MOD=DBEMT Model
TAU1_CONST=DBEMT time constant
Set DBEMT Model to 1 for the constant-tau1 model, set DBEMT Model to 2 to use a model where tau1 varies with time, or set DBEMT Model to 3 to use a continuous-state model with constant tau1.
If DBEMT Model=1 (constant-tau1 model) or DBEMT Model=3 (continuous-state constant-tau1 model), set DBEMT time constant to the time constant to use for DBEMT.
