LS-DYNA originated from the 3D FEA program DYNA3D, developed by Dr. John O. Hallquist at Lawrence Livermore National Laboratory (LLNL) in 1976. [4] DYNA3D was created in order to simulate the impact of the Full Fuzing Option (FUFO) or "Dial-a-yield" nuclear bomb for low altitude release (impact velocity of ~ 40 m/s).
Ansys, Inc. is an American multinational company with its headquarters based in Canonsburg, ... At the time, engineers performed finite element analysis ...
Swanson is the founder of ANSYS, Inc., a John Fritz Medal winner, and a member of the National Academy of Engineering. He is internationally regarded as an authority and pioneer in the application of finite-element methods to engineering. [citation needed]
Margins matter. The more Ansys (NAS: ANSS) keeps of each buck it earns in revenue, the more money it has to invest in growth, fund new strategic plans, or (gasp!) distribute to shareholders.
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.
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 ...
The extended finite element method (XFEM) was developed in 1999 by Ted Belytschko and collaborators, [1] to help alleviate shortcomings of the finite element method and has been used to model the propagation of various discontinuities: strong and weak (material interfaces). The idea behind XFEM is to retain most advantages of meshfree methods ...
1. Tennis Ball. Tennis balls are so useful that you may want to buy some to keep around the house even if you don’t play. For example, half a tennis ball can help screw open tight caps.
