The mesh orientation sensitivity is investigated by diametrically compressing a disc specimen of unstructured meshes from different angles.
In addition, the proposed method shows very low sensitivity to mesh orientation, in contrast with classical finite volume approximation used in porous media flow simulations.
Numerical finite element studies document the avoidance of spurious mesh sensitivity and mesh orientation bias, and demonstrate objectivity and size effect.
We apply this method to several two- and three-dimensional problems in statics and dynamics and show through several numerical examples that the method does not show any "mesh" orientation bias.
Of this combined effect we predict that 24% of it is caused by only turning the mesh orientation whereas 71% of the effect stems from only reducing the number of meshes in circumference.
Simulation examples are designed to verify the efficiency of the tree-cutting algorithm, the calculation's independency from the mesh orientation, and accuracy when modeling porous media that contain fractures with multiple intersections and different orientations.

However, well-developed wrinkling and springback cannot be handled adequately by this method because of mesh-orientation dependence and approximate 3-D bending stiffness.
Different load conditions were applied to the cell to test the effect of stainless steel mesh, cell orientation, methanol concentration and methanol flow rate on transient performance of the cell.
With (a) both units coexisting at all their differing lengths and (b) varying RT increases for both the resulting chains, a mesh-like orientation of these series in the m/z vs. RT plane arises.
The latter is caused by mesh distortions and orientation of the elements relative to the fracture front.
In order to provide quantitative guidance for engineering applications, mesh size and orientation sensitivity are investigated by specially designed numerical tests.
