I have just recently started learning XBeach for my thesis. I
obtained an old 2D model as a point of reference for my learning. I
followed the instructions to download MPICH2 onto my computer
(attached doc to this post). Everytime I run X-Beach, I get an error
with the registration credentials (mpiexec -register). My command
window allows me to type in the username but for some reason I am
unable to type in a password. I was wondering if anyone has some
information on how I should proceed.
