Hello everyone
I am simulating a FSI problem with multiregionsolver.In my case,there are only two regions, solid and fluid.Now I want to use the function setFields to set a quantity ,for example initial volume fraction, in fluid region.
I tried to put the setFieldsDict file in system/fluid floder,then run

setFields -region solid

or

setFields

And it failed.

The following is the details of the file setFieldsDict in my case:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

defaultFieldValues
(
volScalarFieldValue sigma 2
);

regions
(
boxToCell
{
box (-1.1 -1.1 0) (-1.0 1.1 5);
fieldValues
(
volScalarFieldValue sigma 0.01
);
}

boxToCell
{
box (1.0 -1.1 0) (1.1 1.1 5);
fieldValues
(
volScalarFieldValue sigma 0.01
);
}
);

// ************************************************** **** //

So where should I put the setFieldsDict and how to modified it?

regards!
