How to change the deltaT of the simulation

I am a new user of palabos and want to know how to change or setup the deltaT of the simulation.

For example, I can get the deltaT by the function IncomprFlowParam::getDeltaT(). However, I did not find a way to setup deltaT and guess which is determined by palabos automaticly with the formula. I want to change deltaT during the simulation without increasing the domain resolution. Any suggestion?

Thanks very mush.


lattice velocity = IncomprFlowParam::getDeltaT() / the domain resolution. So, change lattice velocity
