Hello, thank you for your concern. It's the first analysis I launch so I don't know what you're talking about with these English. I attach a compressed folder with all generated files and .hm file https://www.dropbox.com/s/rqhp3xmepw8tbnl/ccccc.zip?dl=0 . the file as you will see is not complete but I am proceeding by degrees to understand the various errors
in your launch file there is a set (a list of items) blank is set #2 see below an extract from your launch file. I can't tell you anything else because I use nastran and patran and not hyperworks. many things are similar. Not others.
But basic you have to understand what the test set is a1 and see why it has no elements inside it.
At that point, either you put some elements or delete it,
$$hmset 2 2 "prova a1"
$hmsettype 2 "formula"
set 2 elem list
