I'm wondering if there is a lagrangian solver for N-S.For the motion of a cylinder when the lagrangian approach is used a singularity arises when the cylinder has moved 0.75 times its diameter . I'm interested in studying the propagation of this point of singularity.

Any suggestions welcome.

KIVA is derived from an ALE (Arbitrary Langrangian Eulerian) solver that allows piston motion to drive mesh movement.

I'm told it's not a code for the faint-hearted : ).

KIVA was originally developed at the Los Alamos National Lab, in New Mexico. I believe work continues at the University of Wisconsin. And Cummins Diesel (Columbus, Indiana) and General Motors Corp have a continuing interest.
