To specify the dynamic blade element momentum (DBEM) theory options.
Refer to Dynamic Wake in the AeroDyn program documentation 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.

DBEMT Model: |
The options are Constant Tau1, Time Varying Tau1 and Continuous State. |
DBEMT time constant: |
The time constant to be used when DBEMT Model is Constant Tau1 or Continuous State. |
