AB  - In   this   paper   the   problem   of   simulation   ofdifferential-algebraic  systems  is  addressed.  In  modelling  me-chanical  systems  the  use  of  redundant  coordinates  and  con-straints  results  in  differential-algebraic  equations,  the  integra-tion  of  which  can  lead  to  numerical  instabilities,  such  as  theso-called  drift  phenomenon.  In  [1]  the  authors  have  proposeda  globally  convergent  conceptual  continuous-time  algorithmfor  the  integration  of  constrained  mechanical  systems  whichensures the existence of solutions and global attractivity of thesolution  manifold.  The  objective  of  this  paper  is  to  study  thenumerical implementation of the algorithm presented in [1]. Inaddition,  the  stability  properties  of  the  constrained  system  inthe  manifold  are  studied  in  both  the  continuous  and  discretetime  cases.  The  proposed  technique  is  illustrated  by  means  ofa  simple  example.
