A simple solution for the mentioned example / problem is to slowly and smoothly increase the inflow velocity form zero to the desired value. So you may chose a longer initialization time by e.g. change
int iTmaxStart = converter.getLatticeTime( maxPhysT*0.4 );
into
int iTmaxStart = converter.getLatticeTime( maxPhysT*0.8 );
Best
