Finite Element software Z-set : new web page

New web page of Finite Element Analysis software Z-set is now open: http://zset-software.com/
What is Z-set

Z-set is a computational code devoted to the analysis of material and
structure behavior, involving a finite element solver and a collection
of specific tools for material parameter calibration, preprocessing and
postprocessing computations. Z-set is the result of 30 years of close collaboration between the

1D modeling of tubes in a tube plate assembly.

hello, I am new to the forum, Hi to all

For the last couple of months I have been struggeling with modeling and coupling of 1D elements with 3Delements of a tube plate, 1D elements are chosen because of obvious reasons, we would like to reduces the mesh.

Isogeometric Analysis (IGA)

The aim of this post is to give a brief introduction to the recently emerged isogeometric analysis (IGA) which was presented in the seminal paper " Hughes, T.J.R.; J.A. Cottrell, Y. Bazilevs (2005). "Isogeometric analysis: CAD, finite elements, NURBS,exact geometry and mesh refinement". Comput. Methods Appl. Mech. Engrg. (Elsevier) 194: 4135–4195." IGA refers to a computational framework in which the basis functions used to represent the geometry in CAD are used for approximating the unknown fields in FEA. In this regard, IGA also employs the well known isoparametric concept.

Simulation of Hail Impact Using the Smoothed Particle Hydrodynamic Method in Abaqus/Explicit

Ice or hail impact is an important design consideration in the aviation, energy, and astronautics industries.  Physical testing of impact scenarios can be expensive and impractical.  Numerical simulations provide cost effective and convenient tools for including hail impact scenarios in the design process.

Numerically simulating high speed ice or hail impact is challenging because of the extreme deformation, fragmentation, contact, and material model complexity.

Technology Brief: Optimization of Turbine Blade Dovetail Geometries Using Abaqus and Isight

The reliability of a gas or steam turbine is strongly
dependent on the blade structural design. 
Turbine blades are subjected
to very strenuous environments such as high temperatures, high stresses, and a
potentially high vibration environment. To avoid blade failures, they must be
designed to withstand these conditions.

Traction Prediction of a Smooth Rigid Wheel in Soil using Coupled Eulerian-Lagrangian Analysis - 2012

The approach to modeling soil is validated by comparing predicted traction of a trolling rigid wheel to measured traction test date available in the literature. Comparison of the measured and predicted traction force shows that this approach is reasonable for predictin traction in soil.

Structural Topology Optimization of Multilink Suspension System Using ATOM - 2012

This study demonstrates a simulation of an integrated multilink suspension system model in
Abaqus. The model is assessed in Abaqus to determine the suspension strength and fatigue life of each individual link. This topological design optimization is executed for this multilink suspension model using ATOM to determine the critical load path, alternative concept designs, and locations for mass reduction in order to meet the performance requirements.
