It's been my observation that blueCFD-Core appears not to have the whitespace issues that the official OpenFoam Docker based solution does. This is relevant because most Windows users have a space in their user folder name, which may not seem like an issue, but renaming a Windows user folder is beyond most Windows users' technical experience and skill.

While the user name itself can be renamed through the graphical user interface, renaming the user folder itself requires the creation of a temporary Administrator-raised user--as well as a registry hack.

I implore OpenFoam to move past the current Docker-based solution, toward a native cross-platform solution that would best show off their programming abilities.

Yes, blueCFD-Core was designed to work with spaces in files and folder names on Windows, but it's not yet bulletproof on that front. And to give credit where it's due, a good part of it was inherited from Richard Smith's (Symscape) work on porting OpenFOAM to Windows.

OpenFOAM.com v1812 does provide a bit better support for spaces in folder/file names, as reported here: https://www.openfoam.com/releases/op...ty-portability - section "Improvements in portability" - although it still requires that symbolic links should be created to solve some situations... which might not be very practical in many situations.

Wyldckat, I cannot ask you in an open forum what politics and rational were involved OpenFoam's decision not to do what needs to be done to make OpenFoam Windows-compatable, given that the information, the gatchas, and maybe even the source code is out there.

It is a baffling decision to use Docker on the Windows version.

[As a former Microware OS9 enthusiast, I have no love for Microsoft, Apple, or Linux, so I feel I can call 'em like I see them.

As far as I remember, at one time Silicon Graphics was a competitor to Microsoft, making high-end workstations like the Indigo. The indigo ran on a form of Unix. Perhaps it is unpalatable for SGI/Openfoam to support the platform that contributed to their...dormancy, though some of that credit goes to 3dfx for popularizing the ironically OpenGL-compatable video cards that launched the entire inverted pyramid of Windows-compatable workstations, gaming computers, and GPU supercomputers we see today.

Quick note: OpenCFD is currently ongoing development for making OpenFOAM to cross-compile on Linux to run on Windows: https://develop.openfoam.com/Develop...us/issues/1238


edit: What this means is that it will be built on Linux, but then runs without any virtualization-type things on Windows.

Thank you for the news. I think that in the long run OpenFoam may gain more programmers for it.

I imagine that what BlueCFD-Core did could help.

For years I have been badgering them about this. It looks like I will have to find something else to do. Perhaps I will have more time for CFD studies.

Docker, as a company appears to be in financial trouble.
