[aspect-devel] About the ASPECT output dynamic topography file.

Shangxin,

your question and follow-ups are probably better asked on the ASPECT
mailinglist, so I am cc'ing my answer there.

Yes, that is correct.

I am not the person to who developed this plugin and I am not sure
what you are hoping to see with different "element orders".

Best,
Timo
