ANSYS Mechanical APDL - (*.sub and MADDX files)

[kdtsav]

Dear Friends,

I have a model.db and I have given a *.sub file and a MADDX.ANS file. Do you have any idea how to open these in ANSYS. What exactly is the sequence of opening them, and how can I check that I did it right.
So far I am trying with FILE>LIST>BINARY FILES.... and FILE?ANSYS FILE OPTIONS>... and it seems that it is working, however, there are not differences on my model. How can I check that?

Thanks,
Kostas
