Wind Engineering (WE-UQ) / Re: PimpleFoam freezes in first timestep when using turbulentDFSEMInlet
« on: September 30, 2021, 08:05:07 PM »
Thanks Ajay. Sorry for the late reply.

I was running it on multiple processors. I retried it with the original full case and it seems to run without any issue now. This may be related to the decomposition you mentioned.

Update:
The inlet turbulent generation process seems to be sensitive to the number of cells in the whole domain. I trimmed down the domain to the region near inlet plane and the program works. Now I am planning to store the inlet field and replace the turbulentDFSEMInlet with timeVaryingMappedFixedValue so I can run it on the whole domain.

Wind Engineering (WE-UQ) / PimpleFoam freezes in first timestep when using turbulentDFSEMInlet
« on: September 14, 2021, 10:37:00 PM »
I was using PimpleFoam with turbulentDFSEMInlet on a supercomputer and the simulation freezes at the first timestep. Has anyone experienced this before? Is there any way I can use to debug this?

Wind Engineering (WE-UQ) / Encountering token type error with TInF tool
« on: September 22, 2020, 02:26:20 PM »
Hi all,

I used the TInF tool to modify my pisoFoam inlet files with synthetic eddy case with the default settings. When I try to run my case, I am getting the following token type error at the renumbering step:

[8] --> FOAM FATAL IO ERROR:
[8] wrong token type - expected Scalar, found on line 0 the punctuation token '('[36]

Does anyone know what could cause this problem and how should I debug it?

I have attached the log and inflowProperties File below:

Wind Engineering (WE-UQ) / Building WE-UQ server on alternative HPC
« on: August 07, 2020, 06:20:51 PM »
We are researchers from Canada and have only base allocation on Stampede2, which may not be adequate to run many CFD simulations.

However, we have access to a Canadian supercomputer, Niagara. Do you know if it is currently possible to build a WE-UQ server on an alternative HPC which runs on Linux CentOS 7?
Is there any complication in doing so?

Thank you!

Wind Engineering (WE-UQ) / Errors encountered Running CFDBeginner at DesignSafe
« on: August 04, 2020, 04:13:16 PM »
Hi all,

I tried to run CFDBeginner.json from the workshop, the job started at DesignSafe with no problem.
But when I retrieve the results,  all the outputs are giving nan values for the mean.

I checked the simulation directory and it looks like the CFD simulation didn't run (I can see only step 0 directory). I have attached the log files in this thread.
Does anyone know how I can fix this?

Thanks.

Jack
