Hi,

I got messages about 'singular matrix' and warning about invert mesh while solving ALE problem.

From the attached image file,

I think that the lack of mesh causes this problem.(there was sharp peak )

And there may be the Boundary condition problem.

Any comments will be appreciated .

Thanks
