2D heat equation with varying kappa V2

Thanks for your post, after searching hours, I succeeded to run the docker on my windows 10 computer.
But once Docker is started correctly, from the command prompt of this Docker, when I type the specified command " curl -s https://get.fenicsproject.org | bash" to download fenics,

Error is : the term ‘bash’ is not recognized as the name of the cmdlet …"

This post
Installation issue about bash
reports this issue because “The fenicsproject script does not work in Windows PowerShell or in the Command Prompt ( cmd )”.
They recommand to use “straight docker commands instead”

Question: How do I use straight docker commands ?
(when I started my Docker-Desktop for windows, I have only a command Prompt (cmd) to type commands in the Docker),

Thanks
