I tried to compiled it on OpenFoam 1912, and the following line in "dynamicMultiDimRefineFvMesh.C" prevented from compiling "libdynamicLoadBalanceFvMesh.so":

const label oldPointi = iter.object();

it has to be:

const label oldPointi = iter();

I still have to check that everything works correctly but: is there a particular reason to add the ".object()"?

When compiling with OpenFOAM v2106, I also had to make this change. Additionally, I got a compiler error in the Foam::dynamicMultiDimRefineFvMesh::writeObject function (also in dynamicMultiDimRefineFvMesh.C).

On line 1290, I replace:

dynamicFvMesh::writeObject(fmt, ver, cmp, valid)

by

dynamicFvMesh::writeObject(IOstreamOption(fmt, cmp, ver), valid)

in order to combine the fmt, cmp and ver variables into a single container. This seems to work fine.

Kind regards,

Hi all,

I am running into an issue when using the Load balancing library in OpenFOAM v2206. I use the AMR to refine my mesh near a gas-liquid interface in simulations with the interIsoFoam solver. I want to use load balancing because the interface is not uniformly distributed over my domain.


For smaller test cases I have had no issues with the load balancing functionality. For a larger case (3.5 million cells), I run into an issue (but I'm not sure if the issue is related to the size of the case). I'm running my case on 128 processors, and for the first several thousand time steps all goes well, including the load balancing, which is performed at least ten times.
At some point though, while redistributing the mesh after a load balance step, something strange happens. 126 out of 128 processors still receive a very similar load. However, there is one processor that is assigned zero cells, and one that receives twice as many cells as all the others.

After this, the current time step is finished, but a new time step is never started. The simulation does not crash, there is no error or warning message. It just seems to get stuck in an infinite loop (perhaps related to the assignment of zero cells to a processor?).

There are no obvious clues for me in the log files as to why this happens. I have seen the issue both on the national supercomputer (Snellius) and my universities local cluster. I use scotch for the domain decomposition and redistribution.

I'm wondering if anyone else has had a similar issue?

Hi all,

I'm trying to compile the library dynamicAMR (https://github.com/HenningScheufler/multiDimAMR) in openfoam2312 but I receive several errors. The first one is "error: ‘meshConstructorTable’ is not a class, namespace, or enumeration". Have someone compiled the library to more recent version of opefoam?

Hi Marko,

Have a look at my post from 12-12-2022 in this thread. With the change mentioned by S_teph_2000 and the ones I mention in my post, the library compiled properly for v2206 (though be aware of the issue I described in my latest post here).

With these changes, it also compiles for v2406, though you will get a bunch of compilation warnings, mostly related to parallel communication. My guess is therefore that you will manage for v2312 as well.

Kind regards,
Dennis

Hi Dennis,

thank you for your quick reply. I followed your suggestion, however I'm still facing the same issues. I'm receiving several errors. Am I missing something?
Kind regards,
Marco
