[Other] a problem of dynamicMesh

I'm using dynamicMesh to calculate the flow field of a swimming tadpole.Why do the mesh at the tail become like this?

dynamicMeshDict:

Code:

dynamicFvMesh dynamicMotionSolverFvMesh;
motionSolverLibs ("libfvMotionSolvers.so");
solver displacementLaplacian;
displacementLaplacianCoeffs
{
diffusivity  quadratic inverseDistance 1 (wing);
}

Greetings Gengtian and welcome to the forum!

My guess is that you didn't configure properly all files that relate to the dynamic mesh configuration. Please provide more details, as explained here: http://www.cfd-online.com/Forums/ope...-get-help.html

Best regards,
Bruno
