Convergence problems in Abaqus-Fortran

convergence problems
thermal analysis

Hi mechanicians:



I decided to post because I have an inconvenience that is not shown in other posts.



I am working in the Abaqus - Fortran environment in a thermal analysis. After implementing a new procedure (which actually works), the .sta file shows me that it has problems in its unique step, more or less in the 60th iteration (it is supposed to get until 500). Twenty iterations after that gets into interruptions because the code cannot converge.



With these lines it is easier to understand my point:

finite element modeling
molecular dynamic modeling

The Biosystems and Biomaterials Group at NIST has two postdoctoral positions available for recent PhD graduate to work on (1) simulation of photon transport (light migration) in polymeric composites (2) modeling of cell-material adhesive interactions. These interdisciplinary research programs require the prospective applicants to have a strong background in computational methods (finite element or MD). For the cell-material interaction, candidates with prior experience on biophysics are preferred.

What do
Guitar Strings Have to do With Dynamic Response?

Tightening
guitar strings to change the sound uses the same principle as tightening head
bolts to change the dynamic response of an engine block assembly. This is
stress stiffening and it affects the dynamic response of a structure. One of
the fundamental components in assessing nonlinear static stress is stress
stiffening, but it is also the most overlooked when evaluating the steady-state
dynamic response of engine assemblies.
