CFD Online Discussion Forums - problem with time and velocity data table (interdymfoam)

Hello all

I am using interdymfoam (openfoam 2.1.1) in order to model a kind of seashore wave in a wave maker so i have used a moving wall as a piston like a wave maker.
I have time vs velocity data in each time step but not the velocity function,in fact the function has made of a bunch of functions itself so i can't use groovyBC or wave2Foam boundary condition .i want to use uniformFixedValue BC for that like what is shown in below address
http://www.openfoam.org/version2.1.0...conditions.php

i have inserted only pointMotionUx and U file for this case so for moving wall pointMotionUx is like this

Quote:

moving wall
{
type uniformFixedValue
uniformValue table
(
( 0 0.0)
(100 10.0)
);
}

and for U:

Quote:

moving wall
{
type uniformFixedValue
uniformValue table
(
( 0 (0 0 0))
(100 (10.0 0 0))
);
}

I have tried all uniformFixedValue types in that address but i get this error every time.

I wish you could help me to find what the problem is.
Thanks.
