hello i am a beginner of openfoam !

To run the weiroverflow example related to water injection, i modified some parts of original weiroverflow tutorial code. so i made 2(m) * 2(m) square geometry (2D analysis), and set the left edge as inlet, bottom and right edge as walls, top edge as atmosphere. and i want to time varying water injection, so i modified the alpha.water and velocity (U) boundary condition of "inlet" in original code.

modified contents about inlet are below

[alpha water]


boundaryField
{
inlet1
{
type variableHeightFlowRate;
lowerBound 0;
upperBound 1;
value uniform 0;
}


}


[U]


boundaryField
{
inlet1
{

type variableHeightFlowRateInletVelocity;
alpha alpha.water;
value uniform (0 0 0);
flowRate table
(
(0 0)
(100 0)
(100.01 0.0005)
(200 0.0005)
(200.01 0)
(300 0)
(300.01 0.0005)
(400 0.0005)
(400.01 0)
(500 0)
(500.01 0.0005)
(600 0.0005)
(600.01 0)
(700 0)
(700.01 0.0005)
(800 0.0005)
(800.01 0)
(900 0)
(900.01 0.0005)
(1000 0.0005)
);

}

this worked well !

so to go one step further, in this time, i set the inlet as parts of left edge not all left edge.
Unlike setting the entire left edge (2m) as the inlet condition in my previous code, i only set parts of left edge as inlet (coordinate (-1 0.5 0) ~ (-1 0.9 0) ; inlet length 0.4m), and the others of left edge except inlet are walls
and all condition except this condition are same as previous code.. (vertices of whole square geometry that i used are (-1 -1 0) (-1 1 0) (1 1 0) (1 -1 0))

however in this case, the error occurs.. the contents of error are below.

i didn't understant this error..
can someone tell me what should i do for solving this problem..?

thank you !!
