Hy !-----------------------------------------------! ! ! ! 1--------1 ! ! 1 1 --> ! ! 1--------1 ! ! ! !-----------------------------------------------! I would like to have the same type of geometry where the big tube have a coarse mesh and the small inside square have a very fine mesh.. also I would like that my small square moves in the vector direction with a constant velocity ( and also that he always keep is fine mesh and outside a coarse mesh) Is it possible to do it? What should I use? Mooving mesh?

sorry we cant see the geometry type but I explain it for yyou it is simple there is a big tube with a coarse mesh and inside there is a small square where the mesh inside is very fine and I would like that the small square mooves into my tube with a velocity

hai,

I hope tutorial 11 (two objects passing each other) in STAR-CD manual will help for your application.

shan

thanks But in the tutorial the mooving mesh is a block I wanted to be a fluid and the same tipe of fluid that is inside the big tube is it possible
