WEBINAR - How TURBOdesign Suite enables pump designers to meet emission legislation | Wed 9 March

Submitted by ADT on

In order to meet emission legislation such as EU’s Ecodesign directive or US’s Energy Conservation Standard for Pumps, pump designers need to optimize the efficiency of the pump over multiple operating points. In this 1 hour free webinar we will show how the different modules available in TURBOdesign Suite, especially the 3D inverse design code TURBOdesign1 and automatic optimization platform TURBOdesign Optima can be used to rapidly design high performance pump stages that meet requirement at multiple operating points.

Abstract:

Usermat: Linear viscoelastic model with geometric nonlinearity

Submitted by augustus on

Hello,

I have implemented a linear viscoelastic model using the user subroutine Usermat in Ansys.
I have used the classical paper: "Formulation and implementation of three-dimensional viscoelasticity at small and finite strains" of Kaliske & Rothert (Simo's approach) and it works fine for small deformations.

It is written in the documentation that in the case of a simulation with large strain (geometric nonlinearity), one must rotate the state variables.

The anisotropy of hexagonal close-packed and liquid interface free energy using molecular dynamics simulations based on modified embedded-atom method

Molecular Dynamics; Mg; Solid-liquid interfaces

This work aims to comprehensively study the anisotropy of the hexagonal close-packed (HCP)-liquid interface free energy using molecular dynamics (MD) simulations based on the modified-embedded atom method (MEAM). As a case study, all the simulations are performed for Magnesium (Mg). The solid-liquid coexisting approach is used to accurately calculate the melting point and melting properties. Then, the capillary fluctuation method (CFM) is used to determine the HCP-liquid interface free energy and anisotropy parameters.

Soil nail interaction modeling in abaqus

soil nail interaction
stress strain along nail

Hi,

 

Im modeling soil nail wall subjected to freeze-thaw ( sinusoidal temp variation) by sequentioally coupled temp-displacement., using abaqus .i managed to capture the heat transfer and model the heaving. now im looking to define the interaction between soil and nail in order to obtain stress and strain distribution along nail. however, i donno to define the interaction and their property, was wondering if anyone can give me some advice over the matter ive mentioned.

 

 

Any help is really appreciated
