The abaqus procedure generates several files. Other files contain analysis, postprocessing, and translation results and are retained for use by other analysis options, restarting, or postprocessing. You must handle any file extension conflicts with other applications. It is written by the analysiscontinueand recover options. It is read by the convert and recover options. This file is required for restart. It is written during symmetric model generation by the datacheck and analysis options. It is written by the analysisdatacheckparametercheckand continue options.
This is a temporary scratch file that is used to store the eigenvectors calculated by the Lanczos eigensolver during the solution procedure. The uft file is created only when the unsymmetric solver is used. The ASCII format is convenient for data transfer between machines that do not have compatible binary data formats. It is read when the analysisdatacheckand parametercheck options are selected. This file is written whenever an output database file is opened with write access; it prevents you from having simultaneous write permission to the output database from multiple sources.
It is deleted automatically when the output database file is closed or when the analysis that creates it ends. This is a temporary scratch file that is used to store the Lanczos vectors and weighted Lanczos vectors.
In such a case a process identifier is attached to the file name. It stores a set of internal identifiers for the degrees of freedom in a model. It is written by the analysis and datacheck options. It is read by the analysiscontinueand recover options.
It is written when the input file is parametrized. This file is used to store part and assembly information and is created even if the input file does not contain an assembly definition. The part file is required for restart, import, sequentially coupled thermal-stress analysis, symmetric model generation, and underwater shock analysis, even if the model is not defined in terms of an assembly of part instances. This file may also be needed for submodeling analysis. You must create this type of file to define a parametric study.

File extensions.Combines new modeling, meshing and visualization performance with technology advances for an integrated and flexible FEA software suite.
This release provides further improvements in accuracy, performance and robustness via such developments as new contact formulations and stabilization techniques. Version 6. The Model Tree provides a visual description of the hierarchy of objects in a model and is a convenient tool for navigating and managing finite element models.
The new "view cut" capability allows the analyst to see how results vary inside the model. View cuts can be planar, cylindrical or spherical, or they may be isosurfaces of a specific result quantity. Analyst productivity will also benefit from the new network ODB output data base connector. This feature allows users to access their ABAQUS results files across the network for visualization with little performance degradation, thereby eliminating the need to move the often sizable results to their local desktop computer.
It has been adopted by major corporations across all engineering disciplines as an integral part of their design process. ABAQUS offers a powerful and complete solution for simple to complex linear and nonlinear engineering problems, using the finite element method.
A wide range of structural, thermal and coupled analyses is supported. The software delivers a unified finite element analysis environment without equal, presenting a compelling alternative to implementations involving multiple products and vendors. ABAQUS employs over people worldwide, with 28 direct offices for technical support, sales and services, plus a network of technically advanced distributors in emerging markets.
Customers include automotive and off-highway manufacturers and suppliers; aerospace and defense firms; makers of consumer, electronics and medical products; raw material providers; and companies in the oil and civil engineering industries.

Log In Sign Up.The Abaqus benchmark problems are intended to provide an estimate of the performance that can be expected when running representative Abaqus analysis jobs on different computer platforms.
The different Abaqus products and different types of Abaqus analyses are appropriate for different classes of machines and stress machines differently. The benchmarks are organized with the intention of making it possible for users to view the subset of the benchmark data appropriate to their usage of Abaqus. The benchmark problems listed here are available upon request. Therefore the timing data presented on these pages should not be directly compared with benchmark data obtained using other Abaqus releases.
All times are given in seconds and include the time required for the main analysis executables standard. The Abaqus benchmark suite is designed with the intent of providing users of Abaqus information about how Abaqus will perform on various hardware platforms available on the market.Getting Started With Abaqus - Series of SIMULIA Tutorials
As different Abaqus jobs will stress the hardware in different ways, providing a benchmark suite that is both comprehensive and relatively easy to understand is a challenging task. In order to make good use of the data on this page, users should be careful to understand how the benchmarks are organized and to use data that is representative of their problems. There are two basic variables a user needs to consider when looking at benchmarks.
The first is the type of Abaqus job. Different Abaqus jobs stress hardware in different ways. The second variable a user must consider is the type of hardware being considered. In the following section the basic categories of Abaqus job and hardware used in presenting benchmark data are described. Workstation: The first hardware category is workstations. Typically workstations are single machines with at least 4 cores and 16GB of memory.
Workstations are typically used for running jobs that do not run for a very long time over night being the maximum. In a typical workstation configuration a user is likely to be doing interactive tasks, while the Abaqus job runs in the background. Compute Server: The second hardware category is compute servers.
Computer servers are machines that are dedicated to computing long-running or large Abaqus jobs as efficiently as possible. In past years compute servers were large shared memory SMP machines that were typically shared between many users. More common today are distributed memory DMP compute clusters, where each compute node can function independently or work together to solve a large problem. Compute clusters typically feature a high-speed private network which connects the nodes and a batch scheduler to manage the compute tasks.
A large problem is one with a large number of nodes and elements, or the related measure of number of degrees of freedom. As the size of a problem grows, the cost of an individual iteration, both in terms of runtime and memory requirements, grows, making hardware performance critical to solving large problems.
The runtime, but not memory cost, for a problem is also dictated by the number of iterations required to find a solution. A medium-sized problem may have a very long runtime if the number of iterations required for the problem is very high. As problems grow larger the cost of the linear equation solution will dominate execution time to a greater extent. The Abaqus sparse linear equation solver executes a large number of "BLAS3" type operations which execute well on machines that can very efficiently performance matrix-matrix multiplications.
Element computations are a much bigger factor in smaller problems. Efficient management of element computations tends to stress the ability of a machine to deliver data to the processor in addition to the speed of floating point computation. Both the element computations and linear equation solution can be executed in parallel. Parallelization tends to be more effective with increasing problem size. Problems underdegrees of freedom DOF will typically not show a decrease in execution time when more than 2 cores are used a problem.
Problems under 2 million DOF will typically not show significant speedup beyond 16 cores. Problems with a small number of iterations will also not show good overall speedup with added cores as only the actual iterations are executed in parallel.
The input file preprocessor and initialization code execute on a single core. Linear problems come is several forms.The UEL works perfectly as far as I have time increments each 1e-6 sec. When I'm trying to increase the time increments let's say with the same 1e-6 sec per increment Abaqus gives me error code I'm running Abaqus 6.
CPUs are 3rd generation.
I need to do my final project about bird strike analysis using abaqus. But for now, I try to follow the tutorial from youtube about impact bullet first. For some trial sometimes i found errors and never succeed to solve it. Included the impact bullet trial.
This is what i've got:. Check the procedure and element types used in this model. My model just has one 4-node element defined in UEL fixed in one end. When I'm running the UEL, it's working without any problm. But when I' trying to print out the global stiffness matrix I'm getting this error: " aborted with system error code ".
Would you please help me with that? Thank you very much in advance. Looking forward to your answers. Hello, I have an Abaqus 6. Everything works smoothly. I am easily able to take control of the CAE and model, define loads, steps, sections and jobs. The problem is while running the jobs.
Rarely does the job complete successfully, but I am unable to understand the underlying procedure. I did not request any. This usually indicates an error with the model definition. Additional diagnostic information may be found in the message file. I got the following error msg in Compaq Visual Fortran.
Is there a possible reason for this error as I have gone through my code many times and dont find any suspicious statements that could lead to this error. Skip to main content. Search form Search.Essential tools for your finite element FE analysis!
