Hello Bilal,
Sir, the outdated variables and refinement levels are related?
No, they are not related.
I am bit confused because same warnings are there for 8 refinement levels.
You will see he parameter warnings yes since they are not related to the reflevels.
Precisely, I wanna ask is there any alternative to using old version for encountering out-dated variables.
Unfortunately I am not fully aware of the exact replacement names, I believe the warning gives names of the replace parameters. The values stay the same.
There is a wiki page explaining some of the changes: https://docs.einsteintoolkit.org/et-docs/Rewrite_McLachlan
You may also find out the correct parameters by looking at:
