ParsedSubdomainIDsGenerator
Uses a parsed expression to determine the subdomain ids of included elements.
Overview
The ParsedSubdomainIDsGenerator generator allows the user to specify parsed expressions to compute the subdomain IDs of elements in the mesh.
The parsed expression is provided by "expression", which can a function of the element vertex average coordinates x, y, and z. More importantly, users can use the extra element integer values of each element as the function variables. The names of these extra element integers can be provide through "extra_element_id_names". This feature allows users to assign subdomain IDs based on the values of these extra element integers.
When the subdomain IDs are reassigned by this generator, "excluded_subdomains" can be used to specify a list of subdomains that need to be retained.
Note that due the flexibility provided by the parsed expression, the function value could be a non-integer value or negative. If a negative value is evaluated for an involved element in the mesh, the mesh generator will throw an error. On the other hand, if a non-integer value is evaluated, the rounded function value is used as the subdomain ID.
