Something wrong when using 'runFAST.m'

SYZ622 commented 2 years ago

When I using the 'runFAST.m' to run openfast_simulink, it appears "WARNING: no outputs found in OutList", and " The expression: u(strmatch('Azimuth',OutList)) in 'ROSCO/Cyclic Pitch controller/extract Azimuth' has a syntax error" I don't know how to fix this, and I'd like to get your help. Thanks! Best regards.

Azimuth must be outputted from OpenFAST in the ElastoDyn input.

SYZ622 commented 2 years ago

Thanks for your reply! The Azimuth has been outputted in the ElastoDyn, I think there is something wrong in "WARNING: no outputs found in OutList". I don't know why appearing this warning. When running this code "[Param,Cx] = ReadWrite_FAST(fast);" , the warning appears. It seems the function"ReadWrite_FAST" didn't extract the outputlist.

Here is my code setting. clear;

dzalkind commented 2 years ago

I would set a breakpoint within ReadWrite_FAST and see if the files you're reading exist and if they have an output list. It should be read from here: https://github.com/NREL/ROSCO/blob/51629665d22f92770f861daeebcebd47ab32abb1/Test_Cases/NREL-5MW/NRELOffshrBsline5MW_Onshore_ElastoDyn.dat#L121

void1981 commented 2 years ago

Same thing here. I think the problem is in the OutList itself.

As I run runFAST.m for the fst file ROSCO/Test_Cases/NREL-5MW/NREL-5MW.fst. Before runFAST.m starts the Simulink file simulink/ROSCO.mdl

Out = sim(SimulinkModel, 'StopTime', num2str(simu.TMax)); line 59 in runFAST.m

the OutList has only five cells as follows:

OutList =

  5×1 cell array

    {'Time'     }
    { 1×1 cell  }
    {36×1 cell  }
    { 1×0 double}
    { 0×1 cell  }

This 36x1 cell contains the following:

'"IPDefl1"'
'"TwstDefl1"'
'"BldPitch1"'
'"Azimuth"'
'"RotSpeed"'
'"GenSpeed"'
'"TTDspFA"'
'"TTDspSS"'
'"TTDspTwst"'
'"Spn2MLxb1"'
'"Spn2MLyb1"'
'"RootFxb1"'
'"RootFyb1"'
'"RootFzb1"'
'"RootMxb1"'
'"RootMyb1"'
'"RootMyc1"'
'"RootMyc2"'
'"RootMyc3"'
'"RootMzb1"'
'"RotTorq"'
'"LSSGagMya"'
'"LSSGagMza"'
'"YawBrFxp"'
'"YawBrFyp"'
'"YawBrFzp"'
'"YawBrMxp"'
'"YawBrMyp"'
'"YawBrMzp"'
'"TwrBsFxt"'
'"TwrBsFyt"'
'"TwrBsFzt"'
'"TwrBsMxt"'
'"TwrBsMyt"'
'"TwrBsMzt"'
'"NcIMURAys"'

But inside the Simulink file, they call the outputs directly from the OutList. For example, calling Azimuth as follows: u(strmatch('Azimuth',OutList)) Either rearrange the OutList before running the Simulink file ROSCO.mdl so that it contains the outputs directly or change the calling function u(strmatch('Azimuth',OutList)) so that it points to the output which is not suggested I think as you should do for more than 40 output in Simulink file.

Anyway I guess the whole problem in this code within runFAST.m line 46

for iOut = 2:length(OutList)
    OutList{iOut} = OutList{iOut}(2:end-1); %strip "s
end

Because the OutList after this loop is totally different from what it is supposed to be, even the numbers of cells do not match before and after the loop.

OutList before the loop is like:

OutList =

  5×1 cell array

    {'Time'     }
    { 3×1 cell  }
    {38×1 cell  }
    { 0×0 double}
    { 2×1 cell  }

and after the loop:

OutList =

  5×1 cell array

    {'Time'     }
    { 1×1 cell  }
    {36×1 cell  }
    { 1×0 double}
    { 0×1 cell  }

dzalkind commented 2 years ago

For reference, here is my OutList before the simulation

OutList =

  97×1 cell array

    {'Time'     }
    {'Wind1VelX'}
    {'Wind1VelY'}
    {'Wind1VelZ'}
    {'BldPitch1'}
    {'BldPitch2'}
    {'BldPitch3'}
    {'Azimuth'  }
    {'RotSpeed' }
    {'GenSpeed' }
    {'NacYaw'   }
    {'OoPDefl1' }
    {'IPDefl1'  }
    {'TwstDefl1'}
    {'OoPDefl2' }
    {'IPDefl2'  }
    {'TwstDefl2'}
    {'OoPDefl3' }
    {'IPDefl3'  }
    {'TwstDefl3'}
<lots more>

dzalkind commented 2 years ago

It also looks like you're pointing to the non-simulink NREL-5MW directory fast.FAST_directory = 'E:\OpenFAST\ROSCO-main\ROSCO-main\Test_Cases\NREL-5MW'; % Path to fst directory files

and the Simulink OpenFAST input file fast.FAST_InputFile = '5MW_Land_Simulink.fst'; % FAST input file (ext=.fst)

I suspect the file readers aren't working properly.

is that from runFAST.m code? and which fst file did you use?

https://github.com/NREL/ROSCO/blob/main/Test_Cases/5MW_Land_Simulink/5MW_Land_Simulink.fst

void1981 commented 2 years ago

@dzalkind Could you share with us your runFAST.m file? It is interesting how would it work for you because I had to change the section Premake OutList for Simulink as follows to get rid of this issue.

%% Premake OutList for Simulink

OutList= {'Time'};
OutList2 = {'Time'};
OutList2 = [OutList2;
    Param.IWP.OutList;
    Param.EDP.OutList;
    Param.ADP.OutList;
    Param.SvDP.OutList;
    ];

for iOut = 2:length(OutList2)
    OutList = [OutList;OutList2{iOut}(1:end)]; %strip "s
end

for iOut2 = 1:length(OutList)
OutList{iOut2}=strrep(OutList{iOut2},'"','');
end

Sure it is not perfect but It works. And OutList has only 44 cells when runs 5MW_Land_Simulink.fst by default without any modification on any input files (ElastoDyn, ServoDyn, etc).

SYZ622 commented 2 years ago

@void1981 Thanke for your changed code! I'd like to know which version of ROSCO did you use, and could you share with us your runFAST.m file? It still didn't work when I changed the code like your shared. So the "ROSCO.mdl" has no bug for now, right? Thank you! Best regards,

void1981 commented 2 years ago

@SYZ622 ROSCO 2.6.0 in runFAST.m in section Premake OutList for Simulink change this

%% Premake OutList for Simulink

OutList = {'Time'};
OutList = [OutList;
    Param.IWP.OutList;
    Param.EDP.OutList;
    Param.ADP.OutList;
    Param.SvDP.OutList;
    ];

for iOut = 2:length(OutList)
    OutList{iOut} = OutList{iOut}(2:end-1); %strip "s
end

to this

%% Premake OutList for Simulink

OutList= {'Time'};
OutList2 = {'Time'};
OutList2 = [OutList2;
    Param.IWP.OutList;
    Param.EDP.OutList;
    Param.ADP.OutList;
    Param.SvDP.OutList;
    ];

for iOut = 2:length(OutList2)
    OutList = [OutList;OutList2{iOut}(1:end)]; %strip "s
end

for iOut2 = 1:length(OutList)
OutList{iOut2}=strrep(OutList{iOut2},'"','');
end

do you still get the same issue the expression u(strmatch('Azimuth',OutList)) has a syntax error?

Dear @void1981 , could you please help me to check it?

dzalkind commented 2 years ago

I am using the script currently available on the main branch and OpenFAST version 3.1.0.

I think you would be better off copying the CpCtCq file into the Simulink directory or using this branch, which fixes the relative path issue.

SYZ622 commented 2 years ago

Dear @dzalkind , Thanks for your reply! I have done the copying the CpCtCq file. But there are still two errors. Error due to multiple causes. Caused by: The expression: u(strmatch('Azimuth',OutList)) in 'ROSCO/Cyclic Pitch controller/extract Azimuth' has a syntax error The expression: u(strmatch('BldPitch1',OutList)) in 'ROSCO/Extract Signals/Extract BldPitch1' has a syntax error

But when I changed the section of Premake OutList for Simulink like @void1981 , another error happened, Error in port widths or dimensions. 'Output Port 1' of 'ROSCO/FAST Nonlinear Wind Turbine/Mux1' has 51 elements. This port does not accept the dimensions (or orientation) specified by the output signal. Error in port widths or dimensions. 'Input Port 1' of 'ROSCO/FAST Nonlinear Wind Turbine/S-Function' is a one dimensional vector with 94 elements.

we have the same issue here. I suggested this solution to solve these syntax errors. But actually, this is not the main issue. this is caused by something else which is in the Simulink file ROSCO.mdl.

If you tried to run ROSCO.mdl standalone inside Simulink itself. It has some unconnected ports and blocks. Also, FAST_SFunc block expects different port widths or dimensions.

Capture

what causes these syntax errors is that OpenFAST does not run correctly in the first place. If you looked at the .out file you will see it is empty, therefore there are no data to be read.

I think this last error in S-Function is what causes the whole thing. I have tried to modify ROSCO.mdl a little but couldn't run it correctly. I am using .dll file instead.

icnosvbovwb commented 1 year ago

Dear @void1981 I found a problem that the X64 bit dll with openfast 3.1.0 compiled by myself cannot run ROSCO, but the OpenFAST-Simulink_x64.dll downloaded from github can run ROSCO. I'm not sure why.

Dear @void1981

For the first syntax error with u(strmatch('Azimuth',OutList)), I take this following method:

I am not sure if this is the right way, but it can be running at least currently.

But for your second problem with port widths or dimensions, I also encountered it. Now I'm stuck with this error, did you find any way to resolve it please?
