Hello,

is there a way to use mesh the adaption threshold (in dynamic mode) as a fraction of a current value not the absolute value?

Example:

/adapt/set/refine-mesh? yes
/adapt/set/coarsen-mesh? no
/adapt/set/min-number-cells 1000
/adapt/set/max-number-cells 1500000
/adapt/set/grad-vol-weight 0.85
/adapt/set/max-level-refine 15
/adapt/adapt-to-gradients q-criterion space-gradient 0 1e+4 0 yes 20

Here the adaption occours with a threshold of 1e+4 (actual value is around 1e+5 in the beginning; meaning ratio is 0.1).

Dynamis mode means theat the actual value might be much higher in the end so a fixed threshold isnt really apropriate, but I havent found a solution yet.

Can some kind of a function be used?

Any help would be appreciated.
