Patterns and assemblies
The new Pattern concept introduced in CivilFEM incorporates an own
algebra of structures design.
By means of the definition of Patterns
or cell-structures, it is possible to make complex beam models.
The Patterns
algebra allows the handling of more complex structures (Ensembles) that
can as well be combined using the same logic or algebra.
