<<EOF specify a variable

I use a command in bash such as:
gmx_d energy -f ener.edr -o outfile.xvg <<EOF
1
2
3
4
5
EOF
to print in file outfile.xvg 5 different properties. Is there any way to add a variable such as
gmx_d energy -f ener.edr -o outfile.xvg <<EOF
$i
EOF
and ideally I would like to reproduce the same output with the 5 different properties in the same output file

Why not just do a loop?

You can always include variables in here-documents, and the way is exactly as you have shown. It is just not necessary here.

For your second sample, you'll need to use "<<-".man bash:If the redirection operator is <<-, then all leading tab characters are stripped from input lines and the line containing delimiter.

Since you're trying to provide input (on stdin) to the gmx_d program, pipe it:
printf '%dn' {1..5} | gmx_d energy -f ener.edr -o outfile.xvg
or
seq 5 | gmx_d energy -f ener.edr -o outfile.xvg
