You could do that, of course, but since these will be specific to your environment I can't include such a patch into Flent itself, so you'd have to maintain that patch yourself. An alternative is to use the hex values directly, and couple them with the 'labels' test parameter to get the right plot labels. So you could do this: --test-parameter markings=0x28,0x34,0x38 --test-parameter labels=10,13,15 and that would achieve the same as updating the MARKING_MAP - you just need to keep the order synced between the 'labels' and 'markings' parameter.

You could do that, of course, but since these will be specific to your
environment I can't include such a patch into Flent itself, so you'd
have to maintain that patch yourself.

An alternative is to use the hex values directly, and couple them with
the 'labels' test parameter to get the right plot labels. So you could
do this:

--test-parameter markings=0x28,0x34,0x38 --test-parameter labels=10,13,15

and that would achieve the same as updating the MARKING_MAP - you just
need to keep the order synced between the 'labels' and 'markings'
parameter.

Up to you which one you think is easiest to maintain, I guess :)
