I am trying to address large mesh deformation with tet mesh.

I have searched the web and found that dynamicTopoFvMesh working with mesquiteMotionSolver should be able to replace my current motion solver

"displacementSBRStressFvMotionSolver". I have installed foam-extend 3.1 and ran the tutorial case for dynamicTopoFvMesh: circCylinder3d. But after when T = 1.1s, the process stopped with an error like below:

--> FOAM FATAL IO ERROR:
size 104 is not equal to the given value of 105

file: IStringStream.sourceFile::topWall from line 2 to line 11.

From function Field<Type>::Field(const word& keyword, const dictionary&, const label)
in file /home/zzkzzk2015/foam/foam-extend-3.1/src/foam/lnInclude/Field.C at line 239.

FOAM exiting


I have checked the moving patch data in each time step and found the elements of the patch is 104. But why the elements at T = 1.1s suddenly changes to 105?

Or probably I have used the wrong version of foam-extend?

I am completely new the foam-extend. I hope someone can give me some clues so that I can have an access to the problem.

Thanks a lot
