xpfem

A python package for finite element method (FEM) in solid mechanics

You should download all the code and install the following packages:

• numpy
• scipy
• pyvista

Features:

• linear elasticity
• 2D Quadrilateral element (Q1,Q2)
• 3D Hexahedral element (Q1,Q2)
• BBar element for 3D Q1 element
• Perfect post-processing
• Export VTK file

Run code

You can install the packages by

1. pip install numpy
2. pip install scipy
3. pip install pyvista

Run the test.py or other test file, you can get the displace and stress as following

Preparing input files from ANSYS

See https://github.com/Qinxiaoye/FEM2D to learn how to creat the input files from ANSYS

xpfem's Issues

DEMO没有适配Linux，我用AI帮忙做个脚本处理了一下，分享一下脚本。

1. xpfem目录下做个修改py文件Windows目录路径分隔符的脚本

replace_wintolin_slashes.sh

#!/bin/bash

for file in *.py; do
if [ -f "$file" ]; then
sed -i 's/\///g' "$file"
fi
done

echo "Replacement of \ with / in .py files completed."

执行：replace_wintolin_slashes.sh

2.xpfem/input目录下做个遍历.DAT文件后缀大写变小写的脚本*

rename_suffix_to_lowercase.sh

#!/bin/bash

if [ $# -ne 1 ]; then
echo "Usage: $0 suffix"
exit 1
fi

suffix=$1

find . -type f -name "*.$suffix" | while read -r file; do
dir=$(dirname "$file")
base=$(basename "$file")
new_base=$(echo "$base" | sed "s/.$suffix$/.${suffix,,}/")
if [ "$base" != "$new_base" ]; then
mv "$dir/$base" "$dir/$new_base"
fi
done

echo "File renaming completed."

执行：./rename_suffix_to_lowercase.sh DAT
