SOFTWARE

This software provides the user with the following assets:

• 2-D model simulation

• 3-D model simulation

• Linear Elasticity (Static Analysis)

• Non-linear Plasticity (Transient Analysis)

• Incompressible and compressible fluid analysis

• Transient and stationary simulations for both incompressible and compressible fluids

Main characteristics of the softwar:

• Finite Element Method software based

• Computational Fluid Dynamics Software

• Graphical User Interface (GUI) for  displaying the model and the results (post processing module with basic functions is provided).

• Windows-based software, which can be run in any Windows Operating System: both 32-bit architecture and 64-bit architecture are supported. When run in a 64-bit architecture, the software leverages on the larger word-size when performing computations.

  1. Compatible with Windows 64 bit systems.

  2. Compatible with Windows 32 bit systems

• Graphical User Interface for introducing the geometric domain, physical model, boundary conditions, and displaying the results obtained in any simulation.

• Custom database for storing both the project domain definition and all the information generated during the simulation. 

• Support for NASTRAN format file importing, allowing the user to import any geometry and physical definition in DMAP (Direct Matrix Abstraction Programming) language.

• Vtk file format capabilities, to export generated simulations into ASCII text Vtk files that can be visualized using Paraview

• Basic meshing capabilities to sample the geometric domain. Three methods have been implemented: 

  1. Structured meshing (linear, logarithmic) using both quadrangular elements (QUAD) and triangular elements (TRIA) for regular geometric domains, and 

  2. Delaunay–Voronoi meshing for irregular geometric domains.

  3. Adaptive mesh capabilities, leveraging in the second-order derivative (curvature) of velocity / pressure / energy for remeshing.

• Software designed to run in a computer with a motherboard that may have one or several multicore processors. Parallel computation of the finite element matrices, and parallel assembly of the global matrices of each step in the algorithm. Parallel computation of the right hand side of each step comprising the algorithm. The software uses the conjugate gradient stabilized algorithm provided by the eigen library to solve the linear systems, and it has been compiled with the openmp compiler flag so that the eigen library exploits the multiple cores present in the hardware. 

• Custom user language for post-processing the results (velocity, pressure and temperature), with basic algebra functions and support for different referential coordinate systems. Internal compiler for translating this user language into machine code that can be applied in parallel to every node and / or finite element.

• Supported several types of finite elements (both Lagrangian and Serendipity base functions): 

  1. linear and quadratic TRIA elements.

  2. linear and quadratic QUAD elements.

  3. Linear TETRA Elements

  4. Linear CUBE elements
