Define grid motion: if (time<3*dtime) {} else -

Prikane · March 29, 2016, 08:46

Hello dear colleagues,

currently I am working on one UDF for dynamic mesh, and I was wondering can someone explain me what is the meaning and purpose of the following condition, which has been used in UDF for dynamic mesh (DEFINE_GRID_MOTION):

if (time<3*dtime)
{
}
else
{
}

Also, If someone can explain me what is difference between time and dtime I would very grateful.

Thank you in advance!

Hi
time=current time
dtime=time step
