new_structured_connectivities

Allocate an array of type int filled with the values representing a matrix of 1, 2 or 3 dimensions for the element’s connectivities of tan structured cartesian mesh of lines, quadrilaterals or hexahedra

<nx> is an integer>0 representing the num of grid nodes in x cartesian direction

<ny> and <nz> are the same, for the y and z cartesian directions respectively

<offset_nodes> is an optional integer number (0 default), to be increased to node ids generated (default node_ids start from 0)
