The short answer
Yes! Mia is now part of Dlubal CALC, and with a free CALC account, you receive a monthly allowance of credits (currently 30) that renews every month.
Why does starting Mia from RFEM 6 now open Dlubal CALC?
The new Mia is more than a help assistant. She is a full engineering assistant with direct access to your RFEM model. Starting Mia from RFEM 6 opens CALC so that you can work with all of these new capabilities right away.
