Installation / Re: EE-UQ interface doesn't fit on screen
« on: July 02, 2021, 07:01:46 PM »

Thank you for the feedback and especially thanks for the screenshots.

I do have an idea on what is causing the issue but need a quick test to confirm.  Would you be so kind and try one thing for me: disconnect the second screen and relaunch EE-UQ.  Does that fit properly on your screen then? 


1.     The parameter with the keyword “delta” refers to a characteristic length of a particular fluid flow problem. Its value is mainly dependent on the problem itself. It is usually taken as the  characteristic length of the considered object model (for example, the cross-section width of a building) in the computational domain or one of the dimensions of the computational domain. From my experiences, the determination of this parameter is quite arbitrary.

Would you be so kind to share/attach your OpenSees input file so we can run it ourselves for debugging?


The theoretical requirement is N/n>2 but larger values will increase accuracy.  On the other hand, very large values increase the computational effort for generating the inflow conditions.  N/n >=4 is a recommendation based on experience.

The issue appears to be that directional parameters in InflowProperties must be provided or the code runs into numeric exceptions (1/0 or 0/0).

  • Use the InflowProperties file provided in a post above

  • The OpenFOAM library needs to set sensible default values
  • The OpenFOAM library needs to provide human readable error messages instead of just crashing (all modules)

Would you mind connecting with me via zoom or share a recording showing all your settings so I can reproduce the issue?  This looks like a bug in the OpenFOAM module and will require some debugging on our end.  Having precisely your settings makes tracking and testing easier.



I am not sure if I have the correct set of your files, but the ones I've got from Frank appear to have one missing file: constant/inflowProperties (not saying that this is the only issue.  Might be in our code, too)

I suggest changing 0/U to include:

        type               turbulentDFMInlet;
        filterType         gaussian;
        filterFactor       4;
        gridFactor         1;
        perodicInY         false;
        perodicInZ         true;
        cleanRestart       false;
        calculateU         true;
        calculateL         true;
        calculateR         true;
        value    $internalField;

and add the attached file to constant/.  That file was generated using the SimCenter TInF tool.  The CFD Expert in WE-UQ uses the same engine and should generate the same input file.

Please let me know if that got you any further.  I am available to zoom Friday afternoon or most days next week.

The files you are sharing do not include the turbulence inflow definitions written by TInF.  Did you copy all the (modified) files in the 0, constant, and system folders?  Could you please verify that?

If the problem persists after making sure all files have been properly copied to your project, please create a simple (smallest project that shows the issue) and email me all files from BEFORE and all files from AFTER running TInF as a .zip or .tar file to pmackenz at uw dot edu.  I could further connect via zoom and look at the issue together with you so I can fully understand what is going on.

1) as for uname:

uname is a command, -a is an option to this command.  You need to type  the word uname followed by a space followed by -a.  The output is a string with all the necessary system details.  The gz files are manual pages to be viewed using

man uname

2) the real issue: OpenFoam. 

Your description is very helpful.  It looks like a version incompatibility that requires a fix in the code.   We are looking into this ASAP and keep you informed.  Most likely, we will release source for OpenFoam 6 and one for OpenFoam 7.

Thank you for your patience

Would you be so kind and share
  • exactly which version of OpenFoam you've been using?
  • which version of linux you are using (the output of `uname -a` would be useful)

Hi all,
Could you please post 1-3 sentences (or keywords) that best describe your expectations for the Programming Bootcamp?

That issue may be platform dependent.  I did not see tat issue on a Mac.  If the issue remains, could you please let us know what OS you are using? Thanks!
