Required format of the files

Upload of data is required in .tar format. Create 3 files per simulation:

• 'Name of the team'_'Resolution'_'Phase1'.tar: containing data of the linear growth phase.

• 'Name of the team'_'Resolution'_'Phase2'.tar: containing data of the non-linear evolution phase.

• 'Name of the team'_'Resolution'_'fig'.tar : containing plots and details.

For example Barge_200x600_Phase2.tar

Format of data

The data of each time step is writen in this format:

• the file is named 'number of rotation'.data : for example 012.data for the 12 th rotation

• the file contains in the first line the time, followed by 5 columns containing r, theta, ug, rosg, vortg:

time !the timestep when data are written
r(0)     theta(0)     ug(0,0)     rosg(0,0)    vortg(0,0)
r(0)     theta(1)     ug(0,1)     rosg(0,1)    vortg(0,1)
...
r(i)     theta(j)     ug(i,j)     rosg(i,j)    vortg(i,j)
r(i)     theta(j+1)   ug(i,j+1)   rosg(i,j+1)  vortg(i,j+1)
...

It must have (nx+8)*(ny+8)+1 lines

Plots and details

Plot 2 figures per timestep, and per variable.

• One in (r, theta) coordinates, 'variable'_'number of rotation'.jpg

• One in (x, y) cartesian coordinates, 'cart'_'variable'_'number of rotation'.jpg

For example rosg_012.jpg for (r,theta) representation of density after 12 rotations, and cart_rosg_012.jpg for cartesian representation of density after 12 rotations.

For a good visualisation we recommand to plot:

• rosg*r^3/2, the normalized density

• vortg*r^3/2, the normalized vorticity

Finally, you can write in a file comment.txt the details on the computer used for the runs, and if you used OpenMP, or other parallel code.

For the simulation of 100x300, report the time that was necessary to perform the run. Do not forget to perform this run on 1 processor.
