Mumax documentation is not clear about setting alpha, it is not needed or harmful :
"Relax() tries to evolve the magnetization as closely as possible to the minimum energy state. This function assumes all excitations have been turned off (temperature, electrical current, time-dependent magnetic fields). During relax precession is disabled and the time t does not increase. There is no need to set high damping."
