Dear Philip
I look at to solids4Foam code and twoElasticBeams tutorial. As seen, the new solver can solve multiple elastic interfaces. Also I saw in code, it can define multi material, that is true? do you have any sample about it?
Thanks

Hi

Another question about twoElasticBeams, twoElasticBeams tutorial introduced in development branch. in development branch the fluidSolidInterface.C changed by

// Read interface patches names for regions
// To maintain backwards compatibility, we will first check if a single
// interface pair are defined, then we will check for multiple interface
// pairs

if
(
fsiProperties_.found("solidPatch")
&& fsiProperties_.found("fluidPatch")
&& !fsiProperties_.found("solidPatches")
&& !fsiProperties_.found("fluidPatches")
)
{
solidPatchNames_.setSize(1, word(fsiProperties_.lookup("solidPatch")));
fluidPatchNames_.setSize(1, word(fsiProperties_.lookup("fluidPatch")));
}
else if
(
!fsiProperties_.found("solidPatch")
&& !fsiProperties_.found("fluidPatch")
&& fsiProperties_.found("solidPatches")
&& fsiProperties_.found("fluidPatches")
)
{
solidPatchNames_ = wordList(fsiProperties_.lookup("solidPatches"));
fluidPatchNames_ = wordList(fsiProperties_.lookup("fluidPatches"));

if (solidPatchNames_.size() != fluidPatchNames_.size())
{
FatalErrorIn("fluidSolidInterface::fluidSolidInter face(...)")
<< "Defined number of coupled fluid and solid patches "
<< "must be equal!" << nl
<< "Currently, there are " << solidPatchNames_.size()
<< " solid interface patches and " << fluidPatchNames_.size()
<< " patches!" << abort(FatalError);
}
}
else
{
FatalErrorIn("fluidSolidInterface::fluidSolidInter face(...)")
<< "Either 'solidPatch' and 'fluidPatch' should be defined OR "
<< "'solidPatches' and 'fluidPatches' but not both or neither!"
<< abort(FatalError);
}

solidPatchIndices_.setSize(solidPatchNames_.size() , label(-1));
fluidPatchIndices_.setSize(fluidPatchNames_.size() , label(-1));

In tutorial uses solid/fluidPatches, so the solver should go to elseIf, but in running solids4Foam it take error about keyword solidPatch is not defined in dictionary. Why?
may it due to solidPatch keyword of

// loop over all coupled patches
forAll(solidPatchNames_, interfaceI)
{
// Solid patch index
const polyPatchID solidPatch
(
solidPatchNames_[interfaceI],
solidMesh().boundaryMesh()
);

Hi,

The twoElasticBeams tutorial should work in the master branch. Please pull the latest master branch and check it. If you get an error, please give details of the error.

Hi
I also checked master branch of solids4Foam

the error again is

--> FOAM FATAL IO ERROR:
keyword solidPatch is undefined in dictionary "/home/itp/foam/solids4foam/tutorials/fluidSolidInteraction/beamInCrossFlow/twoElasticBeams/constant/fsiProperties::fixedRelaxationCoeffs|AitkenCoeffs| ISNILSCoeffs"

file: /home/itp/foam/solids4foam/tutorials/fluidSolidInteraction/beamInCrossFlow/twoElasticBeams/constant/fsiProperties::fixedRelaxationCoeffs|AitkenCoeffs| ISNILSCoeffs from line 24 to line 49.

From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 395.

FOAM exiting

A note: In overall tutorial, I think a typing mistake "ISNILSCoeffs" exist in fsiProperties that not essential and unrelated to this topic.

Just checked out the development branch and the tutorial is working properly.

I have checked the log files you send and it seems that the toolkit doesn't compile on your system.

I guess that your system is sill using the old libraries from the last successful compile process which is why the tutorial is not working for you!
This also describes why you can't run any of the feature-coupledTemperatureField's tutorials.

Please report the following:

1- operating system
2- gcc version
3- Does foam-extend itself compile without any error?

No problem with OS, but can you show me which guide you followed to compile foam-extend-4.0?
Because if I remember correctly, foam-extend-4.0 is not compatible with gcc-7.

Although I have personally tested solids4Foam with gcc-5 and gcc-8,
I think that Dr. Cardiff have already resolved issues regrading gcc-7 compatibility.

But you need to be consistent to avoid any ABI compatibility issues, try the following:

• Start clean and fresh
• compile foam-extend-4.0 using this guide and gcc-5: https://openfoamwiki.net/index.php/I...u#Ubuntu_18.04
• The modification in above guide ensures that gcc version is selected correctly when foam-extend environment is sourced.
• Check the log file for any possible error during compile.
• Now start from cleaning solids4Foam directory using Allwclean script and try compiling again.
• It should compile without any issues.

[Hgholami]

Yes. The problem it seen was due to compiler and gcc.
Now I success to run twoElasticbeams tutorial with master branch of solids4Foam.
Thanks
