Hi, everyone!
I'm using the deal.ii library to solve a phase-field model to simulate
columnar dendrite growth during solidification, and several references
proposed a "moving frame method" to improve the computational efficiency.
For example, I employed a 100*500 rectangle computational mesh and the
dendrite will growth in the y direction. Once the distance between the
dendrite tip and the top boundary is less than 100, the bottom region with
a height of 100 is shifted and cut off. The value of the unknown fields in
the shifted region are frozen and saved, while a new region with a height
of 100 should be added onto the top boundary, and the fields in this new
region at this moving time step is konwn. If this "moving frame method"
could be realized by the deal.II library?
Thanks!
