      I am trying to define a node with pre-defined parameters but it is not working.

      p = 1; q =2; r = 3; ii=1;

      iCoMapdlunit.executeCommandToString('N,ii,p,q,r')

      the result shows:

      ans =


      Undefined parameter used for coordinate 3.  A value of 0.0 will be used.

      How to resolve this problem. Thanks in advance.

      The title is a bit confusing - mapdl is an ansys product.
      Is this about using mapdl within matlab?
      I assume here it is aaS in Matlab.
      Try then to type in the numbers for the N command directly:
      iCoMapdlunit.executeCommandToString('N, 1, 1.0, 2.0, 3.0')



      if this works then it is something with the way one is passing in these parameters
      try then to define the xx, yy, and zz as parameters (do not use p as it means pick in apdl, and r is real constant) in apdl:
      iCoMapdlunit.executeCommandToString('xx=1.0')
      and then pass them into the N command
      iCoMapdlunit.executeCommandToString('N, , xx, yy, zz')
      ....


      Fos aaS see this video:

      In the future though I would recommend to use pyAnsys and pyMAPDL


      All the best
