Extract coefficients of Ansatz function from HFSS(eigenmode solver) to Matlab

Hi Everybody,

My question may be too easy for few people in this forum but it would be of great help to me if you can show me way forward.

I modeled pillbox cavity(cylinder) in HFSS to calculate eigen frequencies at first five modes.

Now I would like to export location of nodes as well as corresponding coefficients of ansatz function in ascii file format. Could somebody let me know how to proceed?

Thanks in advance.
