Running the *.psf file in ABAQUS/CAE

Submitted by imangolzad on

Hi all,

I want to use abaqus for parametric study. I have the input file (*.inp) and the python scripting file (*.psf). The problem is that I do not know how to run the *.psf file. I tried the command abaqus script=myfile (the myfile is the file with psf extension) but the error massage (Invalid Syntax) appears.

I would appreciate it if anyone help me to run the *.psf file. Is there any other way rather command line to execute the python scripting file such as *.psf files?

Thanks. 

Nonlocal Instability Analysis of FCC Bulk and (100) Surfaces Under Uniaxial Stretching

The objective of this paper is to examine the instability characteristics of both a bulk FCC crystal  and a (100) surface of an FCC crystal under uniaxial stretching along a <100> direction using an atomistic-based nonlocal instability criterion.  By comparison to benchmark atomistic simulations, we demonstrate that for both the FCC bulk and (100) surface, about 5000-10000 atoms are required in order to obtain an accurate converged value for the instability strain and a converged instability mode.  The instability modes are fundamentally different at the surface as comp

Recent advance in adaptive remeshing techniques now gives the possibility to efficiently simulate complex 3D crack growth using conform meshing of the discontinuity. An exemple of such kind of mixed mode simulation with adpative remeshing can be seen on YouTube:

Determining Graphene Adhesion via Substrate-regulated Morphology of Graphene

Understanding the adhesion between graphene and other materials is crucial for achieving more reliable graphene-based applications in electronic devices and nanocomposites. The ultra-thin profile of graphene, however, poses significant challenge to direct measurement of its adhesion property using conventional approaches. We show that there is a strong correlation between the morphology of graphene on a compliant substrate with patterned surface and the graphene-substrate adhesion.
