Movie 2.

Video of the cell movement in an elongating PSM from the microscpic cellular simulation. On the left we have rigid somites where cells get reected, on the right, we have an elastic chain, representing the Tailbud, which is moving due to active pressure applied by the motile cells. The top and the bottom side has periodic boundary conditions.
