Step-by-Step Tutorial: Homework of Session 2

Hi @ggiraldo, I just wanted to say that I really appreciated your response to this post. It was definitely helpful to understand what was going on, and also a great reminder of vetting simulations and not trusting every pretty fringe plot that’s generated. Thanks.

Oh, this is a really kind answer from your part. I’m so glad I could help a little bit!

Has anyone run into the same problem I have? I finished all the runs (I ran 10 instead of 6, based on the table that was posted), but 3 of the runs are stuck and not producing results. The run status says 100%, but it does not show up in my post processor. And it finished 2 days ago.

Here is a screenshot of an example.

Can someone please help resolve this?

Ok, I have completed the simulaitons and have the results, but when I try to see the solutionfield so visualize the results, my browser just cloggs down for some reason, and can’t go past loading. 8GB RAM and i7 processor, with dedicated GPU as well. I don’t get it, chrome is worse of 'em all. In Firefox I can get to the point where I can select contours and crash. This way I can’t complete the homework to submit.

@Namby - this can happen from time to time if there is an interruption with the server when the simulation is being run (we’re working to fix this). For the three runs that are stuck, I’d suggest creating a new run and re-running it - this should resolve the issue

@rahulsharma_94 - based on the specs your computer should be fine for this, can you try again and let me know? Are you able to see the force plots?

Hi everyone,

Because of my ignorance about the software, i accidentally activated the free trial of the professional pack 12-13 days ago. This pack has only 200 core hours and i have unfortunatelly reached that limit due to the workload of the homeworks.

From what i read, my account will be automatically reset to community plan at the end of the 14 day free trial.

Unfortunatelly, i think that i will not make the deadline because the end of the free trial is sometime tomorrow (or even worse, the day after).

I have done half of the homework though, as you can see in the link below, and it is a matter of just one hour to finish it.

Would it be possible the deadline to get a small extension?

Regards

Hi @kpliontos, I have switched your account back to a community user. The computing quota should be enough right now for you to continue working on the workshop. Please log in again, and check the account status. Feel free to message me, if you need more help! Cheers!

@AnnaFless Yup, it is fine, somewhat, Now the problem occurs, suppose I just added slice from the filter, and If i try adjusting the settings too many times, the browser hangs up. Also selecting the timestep for each of the simulations slows down the loading quite a lot. Anyways I am trying paraview instead. Thanks.

Do we need to use external post-processing or it is just fine to submit the link with the simulation project?

A post was split to a new topic: Feature and Functionality Suggestions for SimScale

@marti, yes it’s fine to submit the project link with the two meshes, as well as the six simulation runs and the force plots.

Hello Anna! I have successfully submitted the Homework for Project 2. I want to know if I can keep working on the same mesh as the surface was not captured properly and I want to investigate the variation of results between original mesh and the refined mesh.

Hi @pgambhir - yes you may definitely continuing working on this. I’m sure others in this forum thread would be interested to see the results as well!

Thanks for clearing that up!

I just wanted to thank you for the explanation on how changing the refinement levels could be worth it as long as we have a considerable difference among the meaningful variables.

Glad I could help.

Hi all,

I could not do this workshop when you were all doing it but I am doing it now. I have done the first part of this session, 3 runs with the rear wing with louvres, however, anyone could tell me how to run the simulations WITHOUT the louvres? Is there another CAD model around? @Milad_Mafi Could you help me with this?

Thank you for your time.
Best,
Victor M.

Hi Victor,

Welcome, hope you are enjoying the workshop so far. I am not sure why the model without lourves was not in the project that you imported. This link should work:

You can download the rear wing 2 geometry from this project and upload it to your current project. Hope that helps!

Best,
Anna

Thank you very much! @AnnaFless, I really appreciate your help.

Best,
Victor M.
