I think that you should use MATLAB to write a piece of code to control the dynamic mesh.

Kamil Jerzy Chodzyński

I was trying to import the project to Matlab but as it takes 4 GB it did not manage. What I need is only to indicate direction of the flow. As it is done for the arrows. I could export data to the txt file but I have 500 time steps then it will take some time. I need to do it somehow in automatic way.
