FEM versus FFT

Submitted by DoQuangHuy on

Dear all,

In micomechanics, homogenization of heterogeneous
materials based on FEM is traditional. Homogenization based on FFT technique has been recently found (in many literatures) to have much more advantages
in term of accuracy, computational cost and resource consumption.

I am wondering why FEMs are still
widely used in education, research, and industries of
generally
computational
mechanics ?

Please could anyone help me to clarify
my question?

Thanks

Volume integration in mehsless methods

Submitted by Mike W. Long on

I use the meshless Galerkin method for 3D simulation of plate movement. This method requires the volume integration over a test domain. Could somebody help me with the volume integration? I wonder if there are standard or open source algorithms that can be used for this problem.

I would appriciate any help.

The SIAM 100-digit challenge of Bronemann et al: A review

Submitted by Mogadalai Gururajan on

Suppose if somebody asked you the following question, and more importantly, wanted the answer to an accuracy of 100-digits:

  • Problem A: A particle at the center of a 10 x 1 rectangle undergoes Brownian motion (i.e., two-dimensional random walk with infinitesimal step lengths) until it hits the boundary. What is the probability that it hits at one of the ends rather than at one of the sides?


Or, this question (again, demanding the answer to an accuracy of 100-digits):
