🔴 linux tip
connect through ssh to the host for the first time
1- generate the ssh key on your computer with the command:
ssh-keygen
This command makes a folder called .ssh in the home folder and two files id_rsa.pub and id_rsa.
2-id_rsa.pub is public key and the id_rsa is private key. Never share the private key!
3- copy the id_rsa.pub to the host (server) in the file .ssh/authorized_keys
now you must have access to the host with the command
ssh username@public_Ip
to configure the public ip of the host, you can use the following command:
ifconfig -a
or
curl ifconfig.me

🔴linux tip
When you are Installing linux on a new made laptop, it is most likely that the wireless is not working. Therefore, you must try LAN or connect with tethering via mobile then install the proper driver for wireless.
In Ubuntu, first check for additional driver in software&update, if there was no driver for wireless, then you must look thoroughly the Linux forums to find a solution. For example in my case, WiFi is not working with Ubuntu 18.04 LTS, 20.4 LTS or Ubuntu 21.04 (latest Ubuntu version), I find the following solution is working for me (Lenovo Thinkpad L15 gen 2).

#python_script #MergeFiles
When a simulation is interrupted and you restart it, swak4Foam prints the data in new time directory (not 0) in postProcessing folder. It is inconvenient for drawing plots to have separated files. The little attached script merges those files in different time directories into single file in directory 0.

I am pleased to announce that our paper entitled
"Bouncing drop impingement on heated hydrophobic surfaces"
has been published in the international journal of heat and mass transfer (#IJHMT) and is now accessible online.
The paper is freely available for the next 50 days - have a look :)

🔴 funkyDoCalc
If you missed run-time processing by an accident, and you don’t like to redo the simulations you may still can derived some results from saved data in time directories. funkyDoCalc is one of utilities accompanied with the package swak4Foam

🔴ساختار اپنفوم پس از نصب
میدونیم اپنفوم یه نرم افزار متن باز هست و ما به تمامی کدهای برنامه دسترسی داریم. توی این ویدیو در این مورد صحبت می کنم که اپنفوم پس از نصب از چه پوشه هایی تشکیل شده! چه ساختاری داره و این که از کجا میشه به فایل های مختلف دسترسی داشت.
