何度か OpenFOAMを installしたが、 チュートリアル動作までは到達せず。
そんな中、 redhat · Wiki · Development / openfoam · GitLab にて
This information unfortunately no longer applies to CentOS-9/RedHat-9. The PowerTools repository has been replaced with a CBR repository with much limited functionality. In the process, they have removed the metis and scotch libraries which are essential for domain decomposition!
という記載を見つけましたので、
OracleLinux8 on WSL2 に OpenFOAM CFD版 ver.2312 を yumでinstallすることに
目次
Oracle Linux 関連
install Oracle Linux 8.7
CMD> wsl --install OracleLinux_8_7 Installing, this may take a few minutes... Please create a default UNIX user account. The username does not need to match your Windows username. For more information visit: https://aka.ms/wslusers Enter new UNIX username: end0tknr Changing password for user end0tknr. New password: Retype new password: passwd: all authentication tokens updated successfully. Installation successful!
systemd & sshd の有効化
/etc/wsl.conf を以下の内容で作成後、OracleLinux再起動
$ sudo vi /etc/wsl.conf [boot] systemd=true
CMD> wsl --terminate OracleLinux_8_7 CMD> wsl -d OracleLinux_8_7 $ ps -ef UID PID PPID C STIME TTY TIME CMD root 1 0 0 07:16 ? 00:00:00 /sbin/init root 2 1 0 07:16 ? 00:00:00 /init ＜略＞ root 30 1 0 07:18 ? 00:00:00 /usr/lib/systemd/systemd-journald ＜略＞
最後にsystemctlでsshdを有効化
$ sudo systemctl enable sshd $ sudo systemctl start sshd
IPアドレスの固定
wsl上のoracle linuxはdefaultでは起動する度にipアドレスが変更され、 sshやsmbでの接続が手間ですので、固定します。
まず、oracle linux側で割当てられているipを確認
$ ip a
＜略＞
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP>
mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 00:15:5d:f4:52:da brd ff:ff:ff:ff:ff:ff
inet 172.18.129.236/20 brd 172.18.143.255 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::215:5dff:fef4:52da/64 scope link
valid_lft forever preferred_lft forever
次に、power shellを管理者モードで起動し、 vEthernet (WSL)の ifIndex を確認した上で、固定ipを設定。

PS> Get-NetAdapter -IncludeHidden Name InterfaceDescription ifIndex ＜略＞ ---- -------------------- ------- : ローカル エリア接続* 7 WAN Miniport (PPPOE) 22 ＜略＞ vEthernet (WSL (Hyper-... Hyper-V Virtual Ethernet Adapter 24 ＜略＞ vSwitch (WSL (Hyper-V ... Hyper-V Virtual Switch Extension Ada... 10 ＜略＞ ＜略＞

IPアドレス固定の自動化
先程、固定したipはpcの停止時に無効化されますので、 ps1ファイルとタスクスケジューラでip固定の自動化を行います
CMD> vi c:/Users/end0t/local/AddIPAddress.ps1 New-NetIPAddress -IPAddress 172.18.129.236 -PrefixLength 24 -InterfaceIndex 24
