Floor:

ceiling:
gradT=0

so I changed 0/T file like this:
"
boundaryField
{
floor
{
type fixedValue;
value uniform 1;
}

rightWall
{

type groovyBC;
variables "y=pos().y; ymax=max(pos().y); T@floor=Th; Tc=0;";
valueExpression "Th-(Th-Tc)*y/ymax";
value uniform 0;
}

leftWall
{
type groovyBC;
variables "y=pos().y; ymax=max(pos().y); T@floor=Th; Tc=0;";
valueExpression "Th-(Th-Tc)*y/ymax";
value uniform 0;
}


movingWall
{
type zeroGradient;
}
"
but when I run, got the error message:

swak4Foam: Allocating new repository for sampledGlobalVariables

Context of the error:

FOAM exiting


did I use groovyBC correctly?
what should I do?

Thanks

finally I found the trouble, I should not use space in variables
