Hi,
Is there a free/open-source mesher for the Spectral Element Method?
I know some researchers use a conventional mesher with order 3 elements
and then include more nodes in the meshes (but without improve the
geometric interpolation).
Thanks in advance,
Hi there,
Doese any one have a working MATLAB code for paticle splitting methods? I have used Monte carlo simulations, Subset simulations etc in the past and am
wanting a more effecient code.
Thanks in advance,

How to find a response for a pinned-(pinned+ torsion spring) column with sinusoidal axial load?
I am unable to decouple the equations in space and time using variable separable method, with one end pinned-other end pinned with torsion spring as boundary conditions.
Can anyone please help.
Good day.

I use abaqus S4R shell element to simulate the pipe bending. How to out the total bending moment at the cross-section?
Recently, a very general and novel class of implicit bodies has been developed to describe the elastic response of solids. It contains as a special subclass the classical Cauchy and Green elastic bodies. Within the class of such bodies, one can obtain through a rigorous approximation, constitutive relations for the linearized strain as a nonlinear function of the stress. Such an approximation is not possible within classical theories of Cauchy and Green elasticity, where the process of linearization will only lead to the classical linearized elastic body.
Abstract
In this paper, we implement the radial basis functions for solving a classical type of time-fractional telegraph equation defined by Caputo sense for (1<α≤2). The presented method which is coupled of the radial basis functions and finite difference scheme achieves the semi-discrete solution. We investigate the stability, convergence and theoretical analysis of the scheme which verify the validity of the proposed method. Numerical results show the simplicity and accuracy of the presented method.

This paper is on my work at Singapore. I think this paper has the following contributions
(1) A concise flow rule is proposed for concrete, every item in the flow rule has clear physical meaning
(2) Let us know that for any material, the flow rule can be simple, and we don't have to pay attention to the potential funcion.
(3) When we propose a plastity constitutive law, we don't have to rely on commercial software like
Abaqus any more, as a numreical calibration method is introduced.
