In the simulation process, when encountering transient large deformations, material failure, and other situations, ANSYS’s explicit dynamics analysis can be utilized to resolve these issues. The ANSYS explicit dynamics module includes three types: Explicit Dynamics, ANSYS AUTODYN, ANSYS LS-DYNA. This article will briefly introduce the specific operations of these three modules through an example. Example … Read more
The Linux Triad consists of the three most important commands in the Linux system, renowned for their powerful functionalities and wide range of applications. The combination of these three tools can almost perfectly address data analysis scenarios in the Shell, hence they are collectively referred to as the Linux Triad. 1. grep grep is a … Read more
Today, I will introduce three commands that are frequently used for text processing in our Linux operating system: grep, awk, and sed, collectively known as the “Three Musketeers of Text” in the community. Each of these commands has its strengths, and when used together, they can efficiently meet various needs for text searching, filtering, and … Read more
The Three Musketeers of Linux grep -n：Print line numbers -A：After, print the N lines after the matched content -B：Before, print the N lines before the matched content -C：Center, print N lines before and after the matched content -E: Support extended regex, e.g., grep -E 'root|nginx' /etc/passwd -v：Invert the match -o：Only print the matched content -w：Exact … Read more
ANSYS is a multipurpose finite element analysis software primarily used to solve problems related to structures, fluids, electricity, electromagnetic fields, and collisions. It is mainly used for linear analysis, nonlinear analysis, highly nonlinear analysis, fluid dynamics analysis, electromagnetic field analysis, acoustic analysis, piezoelectric analysis, and multiphysics coupling analysis. 2. What is APDL? APDL stands for … Read more
Linux File Search 1. Overview of the find Command The need for file searching arises because we often forget the location of a file, and at such times, we need to use the find command to locate it. The find command can search for files based on various criteria, such as file name, file size, … Read more
Awk is a scripting language used for processing data and generating reports. The awk command programming language does not require compilation and allows users to use variables, numeric functions, string functions, and logical operators. Awk is a utility that enables programmers to write small but effective programs in the form of statements that define the … Read more
Printed Circuit Boards (PCBs) are ubiquitous in electronic devices and other related applications. Generally, PCBs are made of multiple layers of laminated materials and resin bonded together. These layers embed conductive metal components and metal vias that pass vertically through these layers. In Finite Element Analysis (FEA), the body and traces in a PCB are … Read more
