Default dynamic mesh

Hi!

I have aproblem regarding dynamic mesh and I hope someone did something similar...

I have two zones where I define grid motion. Let's say that they are two lines that start from different points (A and B)are intersecting somewhere in the domain (in point C). Now...as the time passes the inclination of both lines changes and with that the intersection point C moves (A and B remain constant). I define the lines with a functions like: NODE_X(v) = 5*NODE_Y(v) Fluent always generates a mesh with negative volumes because it doesn't know that I want it to stop grawing a line at the intersection point. Is it possible to make a loop that would define the C point position and "tell" fluent to stop at this point?

I hope I explained the problem well enough, thanks for all the answers, MATEUS
