Hello Aliyu,


Thank you very much for joining on the zoom call & also helping Govind. I am glad to know that the CFD notebooks are now working & you are enjoying it.

This is unfortunately not an error with the Jupyter notebooks. It is an error with the Designsafe Jupyter hub. Could you please try to logout and login again to the Jupyter hub?

Hello Aliyu,


I checked the Jupyter notebooks from Designsafe. They are working. One solution could be to log out of Jupyterhub (see attachment).

Hello Aliyu,


Thanks for letting us know about the issue and also for the screenshots that have been emailed. I will look at this immediately & get back to you by tonight.

Hello Aliyu,


Thanks for the email. I will moved the CFD notebooks topic ot the Educational applications part of the forum. You can find the updates here: http://simcenter-messageboard.designsafe-ci.org/smf/index.php?topic=166.0

I am moving a part of the original post from http://simcenter-messageboard.designsafe-ci.org/smf/index.php?topic=161.0 (related to Jupyter notebooks) to here. Original error:


I have gone through the first CDF-Notebook but encountered error:HTTPError: 401 Client Error: Unauthorized for url: https://agave.designsafe-ci.org/profiles/v2/me

Hydrodynamic Engineering (Hydro-UQ) / Re: Hydro-UQ Crashing
« on: July 30, 2021, 09:16:58 PM »
Hi Emon,


One issue could be that there is an empty row in the Buildings table which is causing it to crash. Maybe you want to delete this row or fill it. Second could be if you tried importing multiple times, that could have caused some issue with the boundary conditions - can you please check that you have only 6 boundaries?


Thanks
Ajay

Hi emon,

Do you think you could share the JSON file with me? You can fill the UI and use the save in the file menu. That should give you the JSON file. If it is even crashing at this point, could you send me a quick screen capture?

Else we could also look at it over a zoom call? Can you send me an email? You can find my contact on the SimCenter webpage (https://simcenter.designsafe-ci.org/about/people/).

Thanks

Hello Aliyu,


Nice to see you at the tool training today. I have some examples in the repo related to today's tool training.


Link: https://github.com/bhajay/Hydro-TT01


I will assimilate this directly into the HydroUQ documentation in the next weeks. Please let me know if there is something that I can help you with.


Thanks
Ajay

Hello Aliyu,


Thanks for your interest. Is there something particular that you would like to try?


We are working on a detailed set of tutorials and it will be released after the tool training.


I can also let you know about the tool training that is coming up in 10 days. The training is on 28-29 July (9 am to 3 pm PST). The link to register for the training is https://www.designsafe-ci.org/learning-center/training/simcenter/2021/studying-coastal-hazards-hydrouq


Please let me know if you have any questions.


Thanks
Ajay

I am writing to you as a follow-up on our discussion during today's programmer meeting. Peter & myself ran Jay's and your examples locally on my Ubuntu VM today morning. Below is a detailed description of all the steps we followed, just in case.

For this, we used OpenFOAM7. I downloaded the TinF from SimCenter Github (https://github.com/NHERI-SimCenter/TurbulenceInflowTool). I used the "wmake" command using the files in the folder openFOAM_code / openFOAM7 / turbulentInflow to compile the libraries.

We compared with Jay's examples provided in the folder tutorials / inhomogeneousTurbulence / DFM / channel395. For the solver here, he has used pimpleFoam. We used both pimpleFoam and pisoFoam and both seem to work and restart. We see that you have renamed the solver as TinFFoam but I hope the linking is correctly done.

Another thing that we noticed was that some items (like Ufinal / kfinal etc.) were missing from the system / fvSolutions dictionary. These were in the original Jay's files but were removed. I am guessing that this was probably unintentional. If we run the files, we get an error message from OpenFOAM that these are missing. So once we added them back, the case started running. We used the procedure outlined by Jay (given below in the attached email) to test the restart operation.

We ran four cases where each had a time increment of 0.2:
(a) Case01: Start time was 0s and end time was 1s (10 steps)
(b) Case12: Start time was 1s and end time was 2s. Here, Case01 was re-started from 1s. So 10 steps.

(c) Case02a: Start time was 0s and end time was 2s.
(d) Case02b: Start time was 0s and end time was 2s


Since there is a random generator being employed, there is a small difference between the results of Case12 and Case02a. In order to confirm this, we ran the case again (Case02b). I have emailed the link for you to download all four cases.


We think that the restart function itself is working correctly. Could you please check again?

I would like to summarize some of the user requests that were provided during the meetings on 16th and 22nd April. The video recording is available for download.


1. Capability to download STL files of the bathymetry to facilitate meshing using external meshing tool & later use these meshes for simulation using Hydro-UQ


2. Ability to change solvers and use alternative solvers to OpenFOAM


3. Allow users to load data from projects that are available on DesignSafe directly into the Hydro-UQ tool. The users could then modify or run the same.


4. Provide tools for designing experiments: (a) A lot of time is spent in designing the waveforms of the fluid. Thus, an ability to correlate the wall motion to the waves produced in the flume can be really helpful.


5. In OpenFOAM we are modeling the complicated structure including its shape. The same is approximated using a frame model in OpenSees. How is the loading transferred? It would help if this can be added to the documentation.

Hi, COuld you please elaborate on it and specify what you are looking for? We could raise it as a user request and add more details on the topic that you're interested in.


Thanks
