At each step, the meshes are refined and coarsened automatically based on geometrical and physical error estimations; the physical fields are transferred from old to the new one using advanced algorithm.
This material is a versatile material applied in many branches of engineering - mechanical, aviation, marine, chemical as well as medical.
At each small load step, the meshes are refined or coarsened automatically according to the constantly changing physical fields and geometrical shape; the element qualities are evaluated and optimized to the regular or similar regular tetrahedral elements; and the physical fields are transferred (point to point) from the old mesh to the new one using advanced algorithm (Fig. 4).

GRC is widely used in construction engineering.
However, the durability of GRC is still a major problem in engineering applications, especially GRC materials have been in the hot and humid building engineering environment for a long time.
It is widely used in the construction engineering industry.
It mainly includes civil engineering, municipal engineering, agricultural engineering, fishery engineering, water conservancy engineering and environmental art, etc [1].

The application of 3D NMM in underground excavation is also presented and show good agreement with real engineering.
The authors [4] have shown that the use of the more advanced Wilson non-conforming element to NMM can be useful in obtaining more accurate results for simple covers.
In the present paper, 3D NMM based on hexahedron meshes is developed which will be useful for practical engineering.
