	Let's try MLSM and described solution procedures first on a lid driven cavity problem that stands for a standard benchmark test for validation of the fluid flow solvers. It has been proposed in 1982 and since then solved by many researchers with wide spectra of different numerical methods. The test is still widely studied and used for validation of novel methods and numerical principles. Case is schematically presented in <xr id="fig:lid_driven_scheme"/> followed by few basic analyses, just to show that things work as they should. Details about comparison can be found in [http://comms.ijs.si/~gkosec/data/papers/29512743.pdf paper]		Let's try MLSM and described solution procedures first on a lid driven cavity problem that stands for a standard benchmark test for validation of the fluid flow solvers.
