Hi There,

I am trying to have a time dependent inlet-condition.
I used the information from the threat "TimeVaryingUniformFixedValue".
(I want the velocity to raise, since pressure corretion messes up when i start up with the high velocity).

But I am stuck somehow...since I dont know how to deal with the error message.

I cant find a missing "(" and there is no value "100000" ->
Any Ideas????

The Error is in the 0/U file, maybe you can show us this one.

Hi Schag,

thx for the answer!!

Ich checked the U file again and tryed things... now it seems to work...(but i ran into other probs , thats why it is called CFD (coloured frustration dynamics :-) ) )

I used the information from:
http://www.idurun.com/?p=506

Where they use:

inlet
{
type timeVaryingUniformFixedValue;
timeDataFileName "inlet.dat";
value uniform 1e5;
}

I used:

inlet-gas
{
type timeVaryingUniformFixedValue;
fileName "inlet.dat";
value uniform 1e5;
outOfBounds clamp;
}

OF seems not to like :
value uniform 1e5;
I removed it and now it seems to be running..

THX a lot!

P.S.:
I had to add the
outOfBounds clamp;
to continue simulation after specified data from "input.dat"..
i found info here : http://albertopassalacqua.com/?p=69
