Beginner + Subroutines

In this Abaqus course for beginners, which is designed for FEM Simulation students in mechanical engineering, various examples in the most widely used fields are presented. These examples are provided with the necessary points and theories for simulation. With this training package, you will be able to get acquainted with different ABAQUS modules in the form of various examples in modeling, how to get the output and the necessary results for reporting. You can download the syllabus of this package here. Watch Demo

This package is usable when the material model is not available in ABAQUS software. If you follow this tutorial package, including standard and explicit solver, you will have the ability to write, debug and verify your subroutine based on customized material to use this in complex structures. These lectures are an introduction to write advanced UMAT and VUMAT subroutines in hyperelastic Martials, Composites and Metal and so on.

This training package helps Abaqus users to prepare complex UMAT and VUMAT subroutines. This Abaqus UMAT tutorial package is suitable for those who are familiar with subroutine or want to learn UMAT/VUMAT subroutine Professionally. Equations for computational plasticity based on kinematic stiffness are also discussed. In addition, metal damage has been implemented based on Johnson Cook's model. Watch Demo

UEL stands for User-defined Elements. When you have a finite element analysis that requires an element type that doesn't exist in the Abaqus element library, you must write a UEL subroutine. Or, when you want to define various element shape functions, the UEL would be the best choice. This subroutine is one of the most sophisticated in the Abaqus and is intended for advanced users. With this tutorial package, you can become an advanced user and learn how to write such a complex subroutine. This package contains two workshops: writing a UEL subroutine for a planar beam element with nonlinear section behavior and writing a UEL subroutine for a beam element with specific boundary conditions and loading.

In this usable tutorial, the material properties can change to an arbitrary dependent variable. One of the most important advantages of this subroutine is simplicity and applicability. Various and high usage examples are unique characteristics of the training package.

This training package includes 5 workshops that help you to fully learn how to use USDFLD and VUSDFLD subroutines in Abaqus software. By means of these subroutines, you will have expertise redefine field variables at a material point by the solution dependence of standard and explicit, respectively.

DFLUX subroutine (VDFLUX Subroutine) is used for thermal loading in various body flux and surface flux states in heat transfer and temperature displacement solvers when flux load is a function of time, place, or other parameters. In this package, you will learn “when do you need to use this subroutine?”, “how to use the DFLUX subroutine”, “what is the difference between DFLUX & VDFLUX?”, “how to convert DFLUX to VDFLUX and vice versa?”, and “How to use it in an example?”. Three workshops are presented so you can learn all these stuff in action: Simulation of welding between two plate with DFLUX subroutine, Simulation of Arc welding between two tube with DFLUX, and Simulation of different types of functional heat flux(Body-surface-Element) in plate with Johnson-cook plasticity with VDFLUX subroutine(Thermomechanical Analysis).

HETVAL is a user subroutine specifically developed to address the limitations of Abaqus in accurately handling volumetric heat flux resulting from internal heat generation within materials. The subroutine’s functionality depends on factors such as time, temperature, or evolving state variables, stored as solution-dependent variables. Accordingly, it can tackle scenarios involving phase changes during simulations. Moreover, the subroutine allows the integration of kinetic theory to account for phase changes associated with internal heat release, such as predicting crystallization in polymer casting processes. Such a multi-functional subroutine finds applications in heat transfer analyses, coupled thermal-electric studies, or temperature-displacement analyses. In this package, our primary goal is to provide valuable insights into the HETVAL subroutine and its diverse applications. Afterward, through a series of comprehensive workshops, we will guide participants in utilizing HETVAL under various conditions. In the final workshop, a problem will be presented, allowing you to explore a realistic example and gain hands-on experience in simulating the curing process within fiber-reinforced composites using HETVAL. Furthermore, to assist those unfamiliar with fiber-reinforced composites, we have included an introductory lesson covering their applications, significance, and an explanation of the importance of accurately simulating the curing process. By completing this package, you will have gained a comprehensive understanding of utilizing HETVAL across various conditions and scenarios. Moreover, you will have acquired the ability to simulate the heat generated during the curing process of fiber-reinforced composites, demonstrating a real-world application of HETVAL.

This training package helps Abaqus users to prepare complex DLoad and VDLoad subroutines. With the help of these workshops, you can get acquainted with the basic and comprehensive way of DLoad and VLoad subroutine writing and their applications. By viewing this package as an engineer, you can do basic projects with complex loads.
