Hi, i have to impose an accelerating flux to simulate a car that is accelerating.

I didn't find guide or something that helps me.

Can anyone explain how to impose a velocity time dependant inlet or send a guide for it?

Thanks really much.

you should be able to setup a time dependent velocity inlet or stagnation inlet and define either a field function or or input table with your t vs v relationship.

Ok. I just want a costant acceleration of 10 m/s^-2. Is this sintax correct?

I just create a new field function "acceleration":

$${acceleration}[1] = 10
$${acceleration}[2] = 0
$${acceleration}[3] = 0

then i create a new field function called VelocityVTime:

$${VelocityVTime}[1] =$${acceleration}[1] *${Time}
$${VelocityVTime}[2] =$${acceleration}[2] *${Time}
$${VelocityVTime}[3] =$${acceleration}[3] *${Time}

is it wrong?

I think your syntax is good... cannot confirm at the moment. Did it work for you?
