MAP_FATAL[40] error

Dear all,

During a normal Simulink simulation, this error has displayed:

Error using Run_Simu (line 21) Error reported by S-function 'FAST_SFunc' in 'FOWT_Simulink_Aerodynamic/FAST Nonlinear FOWT 5MW NREL/S-Function': FAST_Solution:CalcOutputs_And_SolveForInputs:SolveOption2:InflowWind_CalcOutput:CalcOutput:IfW_TSFFWind_CalcOutput [position=(NaN, NaN, NaN) in wind-file coordinates]: Error: FF wind array was exhausted at 236.8 seconds (trying to access data at NaN seconds). CalcOutputs_And_SolveForInputs:SolveOption1:MAP_CalcOutput:MAP_FATAL[40] : Number of function calls has reached or exceeded INNER_MAX_ITS. Line segment 1.

Why can be?

Thank you in advance, JOE

Hi,

As you can see in the error message, it appears that the MAP has 'NaN' entries as it is trying to access data at 'NaN' seconds. You can try the resolutions mentioned in the following post for a solution:

Thanks Ankit,

I was reading that post but is not directly related with my NAN issue. My problem it appears to be from the previous step. My NAN is a result from another program which the output is NAN, so that Matlab can not do the next action if the answer is not a number. I realize late, sorry.

Thankyou anyway, JOE
