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).
