Cremona diagram for a plane truss. The Cremona diagram, also known as the Cremona-Maxwell method, is a graphical method used in statics of trusses to determine the forces in members (graphic statics). The method was developed by the Italian mathematician Luigi Cremona.

Today, nearly every finite element solver available is based on the direct stiffness method. While each program utilizes the same process, many have been streamlined to reduce computation time and reduce the required memory. In order to achieve this, shortcuts have been developed.
While it is difficult to quote the date of the invention of FEM, the method originated from the need to solve complex elasticity and structural analysis problems in civil and aeronautical engineering. [5] Its development can be traced back to work by Alexander Hrennikoff [6] and Richard Courant [7] in the early 1940s.
The global analysis of the system is performed using a finite element solution technique. For a numerical solver to be capable of analysing both flexible materials (such as mooring wires, power cables etc.), and inflexible structures (such as the rigid columns and pontoons of a floating platform), a solution scheme is required which caters for bending stiffness values which are much lower than ...
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 ...
In the context to structural analysis, a structure refers to a body or system of connected parts used to support a load. Important examples related to Civil Engineering include buildings, bridges, and towers; and in other branches of engineering, ship and aircraft frames, tanks, pressure vessels, mechanical systems, and electrical supporting structures are important.
A truss is an assembly of members such as beams, connected by nodes, that creates a rigid structure. [1] In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". [2]
