Hi all,

I am trying to input a termperature field as initial conditions in

abaqus, to use the temperature distribution from a previous temperature

simulation in an mechanical simulation. But when I check the Temperature

values in the mechanical simulation i get great differences between the

nodal values (NT) and the element values (TEMP).

Does anybody know the reason of this problem?

Can it be related to the element typ? So the TEMP values are the avereged values from NT?

In this contribution (see http://arxiv.org/abs/1306.4385), we derive lower and upper bounds for Wachspress coordinates over any simple d-dimensional simple convex polytope.  Numerical results for the Poisson equation on nontrivial polyhedral meshes are presented that affirm the linear rate of convergence in the energy seminorm of the polyhedral finite element method.  Matlab code to compute the Wachspress shape functions and its gradient on convex polygonal and polyhedral elements is also provided.

These two papers (with one on beams and the other on plates) have recently been
published online:

The Automated Computational Mechanics Laboratory (ACML) in the Department of Mechanical and Aerospace Engineering at The Ohio State University has one open PhD position for Spring 2014.  The research in ACML is focused on the implementation of advanced finite element and meshfree methods for the computational modeling of materials with complex geometries, corrosion, damage/fracture mechanics, and multi-physics simulations.
