  Production of domain walls and string-like solitons in the model with two
real scalar fields and potential with at least one saddle point and a local
maximum is considered. The model is regarded as 2-dimensional spatial slices of
3-dimensional entire structures. It is shown that, in the early Universe, both
types of solitons may appear. In addition, the qualitative estimate of the
domain walls and strings formation probabilities is presented. It is found that
the probability of the formation of string-like solitons is suppressed compared
to that of domain walls.
