Dear Xu Yang,

for example in examples/laminar/poiseuille2d and poiseuille3d. You can uncomment //#define ENABLE_MRT to use the MRT dynamics instead of BGK.
Also in the user guide associated with release 1.4 in Section 12.6.6 the necessary changes to run examples/thermal/squareCavity2d and squareCavity3d with MRT are documented.
In case you would like to implement new models or see the currently supported MRT dynamics, please visit the doxygen, type “mrt” and have a look the suggested files.
