Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys. [ 1 ] Engineers use Ansys HFSS primarily to design and simulate high-speed, high-frequency electronics in radar systems, communication systems, satellites, ADAS, microchips, printed circuit boards, IoT ...
Ansys Mechanical finite element analysis software uses computer models to simulate structures, electronics, or machine components to evaluate the strength, toughness, elasticity, temperature distribution, electromagnetism, fluid flow, and other attributes. [8]

The extended finite element method (XFEM), is a numerical technique based on the generalized finite element method (GFEM) and the partition of unity method (PUM). It extends the classical finite element method (FEM) approach by enriching the solution space for solutions to differential equations with discontinuous functions.
A discretization strategy is understood to mean a clearly defined set of procedures that cover (a) the creation of finite element meshes, (b) the definition of basis function on reference elements (also called shape functions), and (c) the mapping of reference elements onto the elements of the mesh.
Nodes are usually placed at the element corners, and if needed for higher accuracy, additional nodes can be placed along the element edges or even within the element. The elements are positioned at the mid-surface of the actual layer thickness. Torus-shaped elements for axisymmetric problems such as membranes, thick plates, shells, and solids ...
In field theory, a primitive element of a finite field GF(q) is a generator of the multiplicative group of the field. In other words, α ∈ GF( q ) is called a primitive element if it is a primitive ( q − 1) th root of unity in GF( q ) ; this means that each non-zero element of GF( q ) can be written as α i for some natural number i .
has units of stress times the root of a distance (e.g. MN/m 3/2). The units of K I c {\displaystyle K_{\mathrm {Ic} }} imply that the fracture stress of the material must be reached over some critical distance in order for K I c {\displaystyle K_{\mathrm {Ic} }} to be reached and crack propagation to occur.
