Abaqus is a software suite for finite element analysis and computer-aided engineering

Abaqus is used in the automotive, aerospace, and industrial products industries. The product is popular with academic and research institutions due to the wide material modeling capability, and the program's ability to be customized. Abaqus also provides a good collection of multiphysics capabilities, such as coupled acoustic-structural, piezoelectric, and structural-pore capabilities, making it attractive for production-level simulations where multiple fields need to be coupled.

Abaqus was initially designed to address non-linear physical behavior; as a result, the package has an extensive range of material models such as elastomeric (rubberlike) material capabilities.

Abaqus - UEL Fortran subroutine accumulating virtual memory space in every iteration

I have a Fortran UEL subroutine that I use in a calculation with just one step but several increments. The model I am calculating is not heavy (2D with about 2000 elements). However, after some increments my calculation stops with the error "forrtl:…

Abaqus strain depedent damping and stiffness

I want to model an equivalent linear soil meterial in Abaqus, which has strain dependent stiffness and damping. The damping due to a stead state analysis, it is better to be of type structural. How can I implement the dependency of stiffness and…

Compile user subroutine only once when running consecutive jobs in Abaqus

I have a script written in Python which calibrates material parameters based on the output of the last job, that is, it runs many jobs in Abaqus consecutively until an error is small enough. I use a Fortran subroutine which compiles before each…

Need help in the following to reduce the execution time

This is just a part of the code, it takes around 5 min for each iteration ( for a single el) to execute. The length of fieldvalues is in the order of 1e6. I believe that multiple appends are eating away the time, Is there any alternative way for…
