Under the menu PlotCtrls > Symbols, you can find the following window where the option ESYS Element coordinate sys you are looking for is available.
As previously answered, it's also available via the following command:
/psymb,esys,1 ! or 0 to remove it.
You can look for /help,/psymb for more information.
You could import the .inp file containing your mesh into Ansys Mechanical APDL, then import your .iges as well (through File/Import/IGES or sometimes Archive Model/Read in /prep7 works smoother), give your attributes to the different areas, mesh them, and export the whole model in .cdb.
Assuming top_beam_n is a component with the upper end node of the beam, top_cyl_n is a component with the upper end nodes of the cylinder, you can do:
Just like any other *get function you can use in APDL, you can loop on each element (or on each element of a group) and fill an array:
Identify maximum number of material properties
Assign material to selected elements

Usually, this type of error doesn't mean there is something "wrong" with node 2144. The finite element solver only discovers the error when it gets to the last node and degree of freedom that it processes, which just happens to be node 2144.
Most likely, there is something wrong with they way the model is constrained, and it can move as a rigid body.
