(Question 1) So should I add a pg2 parameter or is it fine to leave it auto-determined?

It appears all the cases work out.

I'm thinking we can use following to make it more robust:

filename="${topography_file##*/}"
if [[ $filename =~ ne[0-9]+np4pg2+ ]]; then
grid="${BASH_REMATCH[0]}"
echo "grid=${grid}"
else
echo "Pattern not found in filename: $filename"
fi

This will robustly extract the grid substring from filenames with the pattern neXnp4pg2.

grid=${BASH_REMATCH[1]}
echo "grid=${grid}"
if [[ -z "${res}" ]]; then
