Title: Postpone incorporation of user-supplied surface tension to the end 

Zero or negative user-supplied surface tension made the code
crash. Kr(Sw) is indifferent to this value, so it is
a valid fix to postpone the multiplication of surface-tension
to the vector of pressure data to the end of the code,
right before it is printed.
