Hi @rmodrak, there are a couple of things to touch up on the Force example that would be perfect for this PR:

Anything in the comments relative to "Double couple" :

(

mtuq/examples/GridSearch.Force.py

Line 21 in 578f0ce

# Carries out grid search over 64,000 double couple moment tensors

)

mtuq/examples/GridSearch.Force.py

Line 24 in 578f0ce

# mpirun -n <NPROC> python GridSearch.DoubleCouple.py

mtuq/examples/GridSearch.Force.py

Line 26 in 578f0ce

# For a simpler example, see SerialGridSearch.DoubleCouple.py,

for mentions of "moment tensor". There are a few more, you should be able to find them easily with a string search for those terms.

Thanks!
(and thanks @SeismoFelix for noticing this)
