The Material orientation results show the direction in which the material is oriented in the part.
This orientation will effect shrinkage, warpage and direction of impact resistance of the final part.
The orientation of the material is determined by position through part thickness, from the outer surfaces to the part center.
At the surface of the mold, the direction of flow (or shear direction) when the material first meets the surface is the probable orientation direction.
Towards the middle or core of the part, shear and surface cooling has less effect. Radial expansion can be the larger force and so material orientation perpendicular to the flow direction can occur. This will depend on part geometry, the material and any fillers used.
Use this result to determine in which direction warpage will occur due to anisotropic shrinkage.
