Is there any other ways to choose outputs in OpenFAST-Simulink?

[Melancho7ee]

I know that it is recommended to use the "Fcn" block in Simulink to choose outputs, such as u(strmatch('GenPwr',OutList)). I am just wondering if there is any other ways to choose outputs? Can one use the "MATLAB fcn" block to choose outputs?

Dear @Melancho7ee,

I'm not sure I understand your question.

The OpenFAST summary file lists the index of each output stored in the OutList array, so, you can also access the values directly through those indices.

Best regards,

Thanks for your reply. I am trying to output nodal outputs in AeroDyn, such as outputting from u(strmatch('AB1N001Fx',OutList)) to u(strmatch('AB1N019Fx',OutList)). The total 19 parameters are laborious if I use the strmatch methods.
Yesterday I have found a way to solve this problem, shown in the figure below.
Matlab code in the matlab function block is

function y = fcn(u,n1)

y = u(n1:n1+18)

It is simpler to output the 19 outputs, which is what I wanted when I asked this question.
