## Automatic Mesh Function for Heterosis Fem with Modular-Filter Technique (update:31-07-07) (Scripts) Publisher's description

### Generally, in finite element models degree-of-freedom of all nodes be equals.

Generally, in finite element models degree-of-freedom of all nodes be equals. But, a Heterosis finite element model has each of the corners are assumed to possess three degree-of-freedom (one displacement two rotation w,Qxx,Qyy) and centroidal node has two degree-of-freedom (two rotation Qxx,Qyy). In this matlab sub-function application have produced automatic mesh function, position matrix, reology matrix and this matrix components (R and Re matrix) with modular-filter-technique.

Syntax:
mesh_x = "x" axis direction total mesh value.
mesh_y = "y" axis direction total mesh value.
total_x = "x" axis direction total length.
total_y = "y" axis direction total width.

Cor = In global cartesian system all nodes coordinates (xi,yi)
Pos = All nodes position matrisi for each finite element
R,Re = Reology matrix components.
freedom = System total degree-of-freedom.
