Description Daren Sawkey 2021-01-20 12:06:34 CET

The material property GROUPVEL (group velocity) is automatically calculated from material property RINDEX (refractive index), when RINDEX is defined.

However adding an entry to RINDEX with 
MPT->AddEntry(“RINDEX”, e[ie],RINDEX);
does not trigger a recalculation of GROUPVEL.

Thanks to Bernardo Tomé for reporting.

This is now fixed. This functionality is now used in the OpNovice example.
