  We present the Adaptive Aggregation-based Domain Decomposition Multigrid
method extended to the twisted mass fermion discretization action. We show
comparisons of results as a function of tuning the parameters that enter the
twisted mass version of the DDalphaAMG library
(https://github.com/sbacchio/DDalphaAMG). Moreover, we linked the DDalphaAMG
library to the tmLQCD software package and give details on the performance of
the multigrid solver during HMC simulations at the physical point.
