Hi,

I'm curretnly trying to use code wirtten for OpenFOAM 1.1 with my OpenFOAM 4.0 istallation.
I get a lot of error messages when I try to compile.
Here is one example:

In file included from fwd1.C:12:0:
fbcp1-freeBoundary.h: In member function ‘void freeBoundary::store(bool, const scalarField&, Foam::scalar*, Foam::scalar)’:
fbcp1-freeBoundary.h:25:122: error: conversion from ‘const vectorField {aka const Foam::Field<Foam::Vector<double> >}’ to non-scalar type ‘const subField {aka const Foam::SubField<Foam::Vector<double> >}’ requested
  const vectorField::subField bCentres = liquid ? mesh_l->boundary()[fbPatchI_l].Cf() : mesh_s->boundary()[fbPatchI_s].Cf();
                                                                                                                          ^

Where can I find the documentation for functions like boundary() and Cf()? I worked through a few tutorials and used the forums search as well as Google but couldn't find any answers.

Here is another one:

fbcp1-freeBoundary.h: In constructor ‘freeBoundary::freeBoundary(Foam::fvMesh&, Foam::fvMesh&, bool)’:
fbcp1-freeBoundary.h:97:38: error: ‘class Foam::fvMesh’ has no member named ‘allPoints’
  motion_s = new vectorField( mesh_s->allPoints() );

Please give me some hints where to start. What would you do if you wanted to make an OpemFOAM 1.1 code run again?

Thanks for your help!

This is what you're looking for:

I guess you have to change some library links to go with the new one.

Thank you very much for your help!

@anishtain4: the link is very helpful.

I guess you have to change some library links to go with the new one.

@shakil: how can I find out which library links I need to change?
So far, the following libraries are linked:

EXE_LIBS = \
    -lcfdTools \
    -ldynamicMesh \
    -lmeshTools \
    $(WM_DECOMP_LIBS)

However, OpenFOAM 4.0 does not find the library -lcfdTools.

To find out libraries you need to link, go to the the files you have (better to go in the order they will be called through Make/files) read every single #include, if it's not in your directory, search for it in OF root directory. You'll always find some in lnInclude directories.
When Openfoam faces a #inlclude, it first checks your local directory, then $FOAM_SRC/OpenFOAM/lnInclude, and finally the links provided. So if you find something in OpenFOAM/lnInclude, you don't need to link it, but anywhere else you gotta link it.

However, it seems based on your errors this is not the case. Some of the classes has been restructured and you should look up the function in your code to see what it does, and then based on your code how can you update it.
