Hello!

I would like to set the gravitation g in my simulation in the first 0.5 seconds to (0,0,0). Aftwerwards it should switch to (0,0,9.81). I tried it by the us of an if-statement in my g-file with

if(runTime<0.5)
{
value (0 0 0);
}
else
{
value (0 0 9.81);
}

but it doesn't work. Can anybody help me with this issue? Thanks in advance!
