Sandeep,

I built the library for 1.6-ext and ran the same case as before. Everything worked fine!

The difference between installations is, AFAIK, the mesquite version, 2.1.2 versus 2.2.0 for extend and 2.1.x respectively. I'm going to install mesquite 2.1.2 in openFOAM 2.1.x and test the library again.

Hope I'll have news soon

Pablo,

I've committed a couple of bug-fixes and updated the installation instructions. Your case now works with moveDynamicMesh, although it looks like you'll have to play around with the settings a little to get a better looking mesh.

Hi Sandeep,

thank you! Now the 2.1.x branch works as good as the 1.6-ext!!!

I've been working with version 1.6-ext and interDyMFoam since this morning and I could not find the correct configuration to adapt the mesh around the interface. I want to solve the same problem as before but adapting only the interface.

The problem seems to be the map between meshes, since the solver fails trying to solve U, maybe a problem with the fluxes. I have a few questions

1) Which library does the map? Should I use your flux corrector machinery or it is done by another library in openFOAM?

2) When trying to use fluxCorrector Poisson the field rAU must exist. I added this field just copying the definition in interDyMFoam and a dimension problem arises. Any Idea?

3) Do you have a simple test case to use as a start point?

Best

Hi,

Sorry for hijacking the discussion with I find interesting (and by the way I haven't been able to run pablo's case). Anywho, I am interested in running mesquitesolver in OF21x, so far I have been using OF16ext with no problems.

I managed to compile mesquite220 and dynamicTopoFvMesh class with no problems.

Now I am trying to run the case ballTranslation (from the last openfoam workshop) using moveDynamicMesh and I am getting this error

No worries, I found what was the problem, but I think it's odd. Basically it was the order or the motion solver libraries if I use

"libmesquiteMotionSolver.so" "libfvMotionSolvers.so"

It works ok, but if I use

"libfvMotionSolvers.so" "libmesquiteMotionSolver.so"

doesn't work.

In anycase it seems that its working now.

Dear Menon,
I've some work having to do, and I need to compile your src dynamicTopoFvMesh as the pagekage on https://github.com/smenon/dynamicTopoFvMesh to openFOAM 2.1.1. It can be very useful for me. But I faced very difficults to do this. Can you help me (and another users) by creating a user guide to do same work with OpenFOAM 2.1.1?
Thanks very much.
Best Regard.
