I'm trying the second tutorial on OpenFOAM, and I'm getting stuck on literally the first step, running BlockMesh.
My account is an admin account, so I'm getting this message

--> FOAM FATAL IO ERROR: (openfoam-2306)
This code should not be executed by someone with administrator rights for security reasons.
It generates a shared library which is loaded using dlopen



file: system/blockMeshDict at line 17.

From static void Foam::dynamicCode::checkSecurity(const char*, const Foam::dictionary&)
in file db/dynamicLibrary/dynamicCode/dynamicCode.C at line 73.

I found these instructions, but for the life of me I can't find the the files that I would need to edit on my install.

I have a fresh install of v2306, using the Native Windows instructions since that seemed to be the easiest.

Here is where OpenFOAM is installed on my machine: [USER]\AppData\Roaming\ESI-OpenCFD\OpenFOAM\v2306. Can anyone give me some advice?

Two things: never use root (admin) for running any programs beyond administrative tasks - even if you actually trust the sources. Running with dynamic code compilation will probably not work at all if you are using the cross-compiled windows binaries. If they are to work, they would probably need a lot more tools installed (gcc etc).


With the #eval keyword (instead of #calc), there will be no issues - since that keyword uses an internal parser and doesn't compile new code. If you have something like #codeStream etc, you will either have to skip those with the cross-compiled windows binaries or else use WSL and one of the precompiled Linux binaries (eg, for Ubuntu). You will have to make a decision.

Hello Mark ! I’m currently using the Windows version of OpenFOAM (compiled on openSUSE with MinGW), and I was wondering if there have been any updates or progress regarding running the full OpenFOAM natively on Windows. Any insights would be greatly appreciated!

Just change all the `#calc` into `#eval`, then it is working and the blockMesh procedure also faster.
