Volumetric locking

Hi all,
I have a question regrading the volumetric locking in using FEM with COMSOL
I plan to use linear elasticity in COMSOL for the nearly in-compressible material (ex. poisson's ratio, nu=0.49). We all know that this will result in the volumetric locking of the element without any special treatment.
As I know, ANSYS uses "Extra shape function technique" and "Reduced integration technique" in SOLID45 and SOLID185 solvers respectively to overcome the locking.
I would like to know how COMSOL treats the volumetric locking for the incompressible materials
Best wishes,
