• 61% of students did not take the square of tanh (Ut/L) (P4.8).

• 46% of students did not answer why the acceleration become negative in the duct (P4.8), even if required.

• 13% of students recognized the flow as inviscid but did not recognize that it was a uniform stream past a cylinder (P4.25).

• 75% of students did not give any interpretation of the flow (P4.25), even if required.

The success of the random vortex method was exemplified when it was shown to accurately compute flow past a cylinder at the Reynolds numbers up to 9500 in the 1990s [13]

Sharp convergence rates have been found for the random vortex method when applied to the Navier-Stokes equation by Goodman [8] and Long [16].. M i is the mass of the particle X t i,ε
