I have been using a modified version of SU2 v4.1.0 to run RANS-SA simulations of Mach 5 flow. I am now trying to run the same mesh with SU2 v6.2 and I am trying to keep the configuration file and options as consistent as possible.

I am having some confusion surrounding the "REF_ELEM_LENGTH" option from the v4.1 config file. It was set at 0.1 in my config file but I cannot find a way to implement this in v6.2. However, when I run the new config file with SU2 v6.2 (without specifying any reference element length for the slope limiter) the output file still notes "The reference element size is: 1" under "Space Numerical Integration". I am trying to ensure that the simulation is as consistent as possible between versions. Is there a way to implement my choice of REF_ELEM_LENGTH in v6.2?
