hi all
I have been trying to use the mappedVelocityFlux B.C. to map the velocity from the neighbour mesh to the boundary which this condition is applied on. when i use the bellow format (exactly like what said on https://cpp.openfoam.org/v3/a01417.html
melt_to_solid
{
type mappedVelocityFlux;
phi phi;
value uniform 0;
}
i get the following error:
--> FOAM FATAL IO ERROR:
Expected a '(' while reading VectorSpace<Form, Cmpt, Ncmpts>, found on line 43 the label 0

file: /home/armin/OpenFOAM/armin-6/run/Mytut/conjugateStoragezzCompressiblePorous/0/melt/U.boundaryField.melt_to_solid.value at line 43.

From function Foam::Istream& Foam::Istream::readBegin(const char*)
in file db/IOstreams/IOstreams/Istream.C at line 92.

FOAM exiting

I sense the above error is trying to tell me that i have to implement the "value" in vector type so i change my B.C. to the bellow form:

melt_to_solid
{
type mappedVelocityFlux;
phi phi;
value uniform (0 0 0);
}

but this time a rather stranger error shows up:

--> FOAM FATAL ERROR:
hanging pointer at index 4 (size 4), cannot dereference

From function T& Foam::UPtrList<T>:: operator[](Foam::label) [with T = Foam::fvsPatchField<double>; Foam::label = int]

Anyone has a clue what should I do?
I would appreciate any guidance

I dont know about OF6, but are you sure that v3 syntax remained the same in v6, which seems to be you are using.

[ArminAlavi]

Thank you very much for your response. I checked the source code for OF6. it seems that it's syntax has remained unchanged since then.
here is the source code

Hi,

Please look at .C file, which had several changes.

Also, the correct syntax is for 'value' placeholder is 'value uniform 0;'

Could you please check semi-columns/header file above-below of this part of the input?
