Asymmetries-in-coalescence

Asymmetries in coalescence: size asymmetry. Still axially symmetric.

running the codes

There are two ways to run the codes:

1. Using the vanilla basilisk method:

qcc -O2 -Wall -disable-dimensions coalescenceBubble.c -o coalescenceBubble -lm 
./coalescenceBubble

2. Using the makefile (can be interactively run using bview browser):

CFLAGS=-DDISPLAY=-1 make coalescenceBubble.tst

Check the localhost on coalescenceBubble/display.html. something like: http://basilisk.fr/three.js/editor/index.html?ws://localhost:7100 and run interactively.

To run using openMP, please use the flag -fopenmp

qcc -O2 -Wall -disable-dimensions coalescenceBubble.c -o coalescenceBubble -lm -fopenmp
export OMP_NUM_THREADS=8
./coalescenceBubble

Note: The code will not directly work with openmpi (with -D_MPI flag and mpirun). To do that, please follow the procedure we use:

1. Run the following for a few timesteps (stop using tmax=1e-2 or so)

qcc -O2 -Wall -disable-dimensions coalescenceBubble.c -o coalescenceBubble -lm -fopenmp
export OMP_NUM_THREADS=8
./coalescenceBubble

This will generate a "dump" file

2. Do not delete the dump file. Now you can use mpirun, like:

CC99='mpicc -std=c99' qcc -Wall -O2 -D_MPI=1 -disable-dimensions coalescenceBubble.c -o coalescenceBubble -lm
mpirun -np 8 coalescenceBubble
