Hi everyone!

I am running simulations for the 15 MW IEA with Turbsym. I am starting with a turbulent windtype with the following specifications:

--------Turbine/Model Specifications-----------------------

67 NumGrid_Z - Vertical grid-point matrix dimension

65 NumGrid_Y - Horizontal grid-point matrix dimension

0.05 TimeStep - Time step [seconds]

630 AnalysisTime - Length of analysis time series [seconds] (program will add time if necessary: AnalysisTime = MAX(AnalysisTime, UsableTime+GridWidth/MeanHHWS) )

60 UsableTime - Usable length of output time series [seconds] (program will add GridWidth/MeanHHWS seconds unless UsableTime is “ALL”)

150 HubHt - Hub height [m] (should be > 0.5*GridHeight)
260 GridHeight - Grid height [m]
250 GridWidth - Grid width [m] (should be >= 2*(RotorRadius+ShaftLength))

0 VFlowAng - Vertical mean flow (uptilt) angle [degrees]

0 HFlowAng - Horizontal mean flow (skew) angle [degrees]

--------Meteorological Boundary Conditions-------------------

“IECKAI” TurbModel - Turbulence model (“IECKAI”,“IECVKM”,“GP_LLJ”,“NWTCUP”,“SMOOTH”,“WF_UPW”,“WF_07D”,“WF_14D”,“TIDAL”,“API”,“USRINP”,“TIMESR”, or “NONE”)

“UsrSpec.inp” UserFile - Name of the file that contains inputs for user-defined spectra or time series inputs (used only for “USRINP” and “TIMESR” models)

“1-ED3” IECstandard - Number of IEC 61400-x standard (x=1,2, or 3 with optional 61400-1 edition number (i.e. “1-Ed2”) )

“B” IECturbc - IEC turbulence characteristic (“A”, “B”, “C” or the turbulence intensity in percent) (“KHTEST” option with NWTCUP model, not used for other models)

“NTM” IEC_WindType - IEC turbulence type (“NTM”=normal, “xETM”=extreme turbulence, “xEWM1”=extreme 1-year wind, “xEWM50”=extreme 50-year wind, where x=wind turbine class 1, 2, or 3)

“default” ETMc - IEC Extreme Turbulence Model “c” parameter [m/s]

“PL” WindProfileType - Velocity profile type (“LOG”;“PL”=power law;“JET”;“H2L”=Log law for TIDAL model;“API”;“USR”;“TS”;“IEC”=PL on rotor disk, LOG elsewhere; or “default”)

“unused” ProfileFile - Name of the file that contains input profiles for WindProfileType=“USR” and/or TurbModel=“USRVKM” [-]

150 RefHt - Height of the reference velocity (URef) [m]

3 URef - Mean (total) velocity at the reference height [m/s] (or “default” for JET velocity profile) [must be 1-hr mean for API model; otherwise is the mean over AnalysisTime seconds]

“default” ZJetMax - Jet height [m] (used only for JET velocity profile, valid 70-490 m)

0,14 PLExp - Power law exponent [-] (or “default”)

“default” Z0 - Surface roughness length [m] (or “default”)

I have followed the suggestions from the user guide for these parameters. I do not know why, at the time of the simulation with turbsym, the following code in cmd appears for unlimited time:

Running TurbSim (v2.00.07a-bjj, 14-Jun-2016).

Reading the input file “TurbSim_UsrSpec3ms_turb.inp”.

Calculating the spectral and transfer function matrices:

u-component matrices (IEC coherence method)

The v-component matrices and w-component matrices should appear also, but it takes so much time for it to appear (after one hour waiting,it does not appear).

As I said, I have been one hour waiting for it to be run, but still i do not receive the .bts file… Is this because the num_gridZ and num_gridY are large?? If so, is there any chance of making the simulation run in short time?

Thank you
