Simcenter Amesim is a commercial simulation software for the modeling and analysis of multi-domain systems. It is part of systems engineering domain and falls into the mechatronic engineering field.
In numerical analysis, adaptive mesh refinement (AMR) is a method of adapting the accuracy of a solution within certain sensitive or turbulent regions of simulation, dynamically and during the time the solution is being calculated. When solutions are calculated numerically, they are often limited to predetermined quantified grids as in the ...
Simcad Pro - Process simulation software with On-The-Fly model changes while the simulation is running. Lean analysis, VR, and physics. Developed by CreateASoft, Inc. Chicago USA; Simcenter STAR-CCM+ - a computational fluid dynamics based simulation software developed by Siemens Digital Industries Software.
FEM software provides a wide range of simulation options for controlling the complexity of modeling and system analysis. Similarly, the desired level of accuracy required and associated computational time requirements can be managed simultaneously to address most engineering applications.
Flowmaster is a general purpose 1D computational fluid dynamics (CFD) code for modeling and analysis of fluid mechanics in complex piping and ducting systems of any scale. . It is a thermo-fluid systems engineering package that has the ability to simulate flows of gases and liquids, heat and mass transfer, moving bodies, two-phase flows and fluid-structure interaction (FSI) through ...
In a simulation this may be implemented by using small time steps for the simulation, using a fixed number of constraint-solving steps per time step, or solving constraints until they are met by a specific deviation. When approximating the constraints locally to first order, this is the same as the Gauss–Seidel method.
The goal of modal analysis in structural mechanics is to determine the natural mode shapes and frequencies of an object or structure during free vibration.It is common to use the finite element method (FEM) to perform this analysis because, like other calculations using the FEM, the object being analyzed can have arbitrary shape and the results of the calculations are acceptable.
Classic model used for deriving the equations of a mass spring damper model. The mass-spring-damper model consists of discrete mass nodes distributed throughout an object and interconnected via a network of springs and dampers.
