Subject: How to Create Isoparametric Elements
The most common technique for approximating curved geometry in the
finite element method is to use "isoparametric elements". Isoparametric
elements are explained in most finite element textbooks, e.g., Hughes;
Johnson; Zienkiewicz & Taylor.
But I do not know of a good algorithm to compute an isoparametric
interpolant to a curved geometry. Consider the following special case:
a tetrahedral element lies inside a sphere. Three of its vertices are
on the spherical surface and the fourth is interior. I would like a
procedure to curve this element so that its outer surface approximates
spherical geometry to a high order. A naive algorithm that interpolates
the surface using an evenly-spaced mesh of points produces oscillatory
results because of the "Runge" effect. Note that it is desirable not
only for the interpolant to lie close to the true surface, but also for
the normal to the interpolant to lie close to the normal to the true
I imagine that there must already be good published solutions to this

New chapters in the ADDENDUM to Scientific Supercomputing
At first it should be recalled that the basic lecture SCIENTIFIC
SUPERCOMPUTING is now available typed and printed as booklet, see cover
page of the ADDENDUM. The knowledge of this lecture is needed for the
understanding of the following.
The ADDENDUM to Scientific Supercomputing
is an oper-ended supplement of additional short lectures on special
subjects. In the new Version 1.1 new chapters and sections on workstation
processors and SMP servers have been added. Above all we report on our
measurements of actual processors in 1999 and we make an interesting
comparison from the point of view of scientific computing that reveals
meciless the weaknesses of the processors (Chapter A10).
The following sections and chapters have been added:
A3.6 The MIPS R12000 Processor (300 MHz) in the Origin 2000.

Subject: Research Positions at TU Delft
The Departments of Aerodynamics and Engineering Mechanics of the Faculty of
Aerospace Engineering, Delft University of Technology, The Netherlands offer:
in the project
Computation of Fluid-Structure Interactions Applied to Wing Sections
Aim of this interdisciplinary project is the development and implementation
of numerical methods for accurate computation of the interactions between
flow and structure, e.g. wing sections. These interactions concern distortions
of the structure due to forces from the flow, and changes in the fluid flow
pattern due to the moving boundary of the structure. Within this project we
have two funded positions for PhD-students.
Focus of separate positions:
The first position concerns the application of Direct Numerical Simulation
(DNS) to Fluid-Structure Interactions. Main objective is the accurate
computation of transition and separation in flow involved in interactions with
the structure, by applying DNS in a smart way.
The second position concerns the numerical computation of the interactions
between the flow and the wing section. This involves coupling of the
equations for the flow and the structure in time, accurate time integration of
the system(s) of equations, movement of the grid, and space discretisation of
the equations on a moving grid.
The project is a joint project of the Engineering Mechanics group of
prof. R. de Borst and the Aerodynamics group of prof. P.G. Bakker.
Both PhD-students will be working in our Fluid-Structure Interaction team
consisting of three assistant professors. The PhD-students will be able to
participate in the training of the national research school for fluid dynamics:
the J.M Burgers Center.
The duration of both appointments is four years.
A masters or equivalent degree in Mathematics, Physics or Engineering with
a strong background in Computational Fluid Dynamics, Computational Structural
Mechanics or a related discipline is required.
Applications should be submitted to:
