Spherical squirmer has no default direction #300

Closed kevinstratford closed 5 months ago

kevinstratford commented 5 months ago

If the user doesn't set a direction in the input, the direction is a zero vector, which generates no motion.

This is confusing, and should be replaced by a default or an error.

Fixed by #301 in that an error message now appears.

Will go into next release.
