User element (UEL) subroutine (user-defined element) is the highest level of a subroutine that Abaqus offers to its users. This subroutine allows the user to program the basic building block of a finite element simulation. This subroutine becomes very powerful when the user wants to implement a type of element that is not available in Abaqus. Using this subroutine, user can define different types of shape functions, introduce element technology that is not available in Abaqus, or simulate multiphysical behavior that is not possible otherwise.
This Abaqus user element tutorial package will give a brief introduction to the user element subroutine followed by theory and algorithm to write subroutine small strain mechanical analysis. First, we will highlight the UEL element stiffness matrix and element residual vector which are to be programmed in the first example. We will also cover shape functions and numerical integration. Next, we’ll talk about UEL inputs and outputs.
The first example contains the detailed development procedure of a general-purpose subroutine for 2D plane-strain and 3D simulations using triangular, quadrilateral, tetrahedral, and hexahedral type of elements with reduced and full integration scheme. The second example demonstrates the procedure to build UEL-compatible model in Abaqus/CAE. It also demonstrates how to apply complicated boundary conditions with UEL as well as perform Abaqus analysis on structures which has standard and user elements. As an outcome, user can write their own UEL subroutine afterwards using this program as template.

Modal and Frequency Analysis in Abaqus | Abaqus modal Analysis
Modal analysis is a technique used to understand how structures and systems vibrate when subjected to forces. It identifies natural frequencies, which are frequencies at which a system vibrates without external excitation, and mode shapes, representing unique patterns of motion. Engineers use modal analysis simulation to design systems resistant to unwanted vibrations, preventing resonance and potential damage.
Frequency response analysis evaluates a structure's reaction to specific excitations across varying frequencies, aiding in design optimization to mitigate fatigue damage caused by vibrations. In Abaqus software, Abaqus modal analysis identifies natural frequencies (Abaqus natural frequency) and mode shapes, while frequency response analysis predicts a structure's response to excitation across a frequency range.
In Abaqus modal analysis tutorial package, there are several modal analysis examples (modal analysis example): Workshop 1 analyzes the natural frequency of a water transfer tube to predict resonance occurrence or potential issues from vibrations. Workshop 2 simulates the dynamic analysis of a frame under a sudden load, determining modes, natural frequencies, and transient dynamic response.
Workshop 3 simulates free and forced vibrations of a wire under harmonic excitation, examining resonance phenomena with preloading and spring-damper configurations. These workshops demonstrate practical applications of modal and frequency response analyses in structural dynamics simulation and design.

Car part industrial simulation
Car industrial parts are complex and critical components that play a vital role in the operation of a car. Two such parts are the exhaust manifold and the internal combustion engine (IC engine). The exhaust manifold directs hot exhaust gases from the engine's cylinders into the exhaust system and is typically made of cast iron or stainless steel. The IC engine converts fuel into mechanical energy by burning fuel in a controlled explosion within the engine cylinder. High temperatures and pressures must be considered in the design, and the components must be made of durable materials that can withstand the stresses of constant combustion. Therefore, it is important to know how these parts respond under different loading conditions to have the best design possible. In this package, there are two workshops to help you with this job: Heat transfer analysis in an exhaust manifold and Thermomechanical analysis of an exhaust manifold.

Eulerian Abaqus and CEL modeling
The Eulerian method is a numerical technique used to analyze fluid mechanics problems. In this approach, the fluid is treated as a fixed grid, where the nodes remain stationary while the fluid flows through them. The Eulerian Abaqus method can be used to analyze fluid-structure interactions, such as fluid impact on structures or the behavior of fluids in containers. To use the Eulerian method in Abaqus, the desired geometry must first be meshed using Eulerian elements. The material behavior of the fluid is then defined using appropriate equations of state. Finally, the boundary conditions and loading are applied, and the system is solved using the appropriate numerical method, such as the finite element method. This package will teach you how to use this method and various practical examples. Also, this package covers several practical examples in Abaqus CEL method.

Cold spray & Shot peening simulation in Abaqus
Cold spray is a process used to deposit materials onto a substrate by accelerating fine powder particles to high velocities using compressed gas. Upon impact with the substrate, the particles undergo rapid plastic deformation, disrupting surface oxide films and promoting bonding between metal surfaces. Unlike thermal spray processes, cold spray avoids thermal degradation and partial oxidation of the coating material, resulting in coatings with low porosity and oxygen content. The process is highly efficient, with deposition efficiencies often exceeding 90%. Shot peening is a metal treatment process that involves bombarding a surface with small, round metallic (usually steel), ceramic, or glass beads at high velocity. This process creates small indentations on the surface, which in turn introduces compressive residual stress into the material. These two processes are different and use for separate purposes but their simulations are the same.
Cold spray is particularly important in applications where thermal degradation or oxidation of the coating material is a concern or where the coating is required to be thick and free from defects. In this package, you will learn how to simulate this process with different methods, such as ALE and SPH, with different materials. For example, Cold spray simulation of steel particles impacts on the Inconel target using ALE method.
