Hi @gurav_harsh , you missed the webinar i guess. It was at 4 p.m central european summer time ( **CEST** ). In which country do you live (because to the time shift of approx. 3 hours)? The GoToWebseminar.exe will download automatically when you click the link in your email that redirects you to the website of GoToWebinar. Kind regards, Jousef ---

Hey gurav, as mentioned in the [step-by-step tutorial](https://www.simscale.com/forum/t/step-by-step-tutorial-homework-of-session-1-level-1/297) you have to choose a larger number of computing cores. You can change this under **Simulation Control** Cheers, Milad ---

Hello, This class is free and if you have a free account you get unlimited use of the software for the length of the class. I am a paid user with about 500 core hours left and one run of the first part of homework 1 took almost 20 core hours. I can see this class using most of the core hours I have left. Are the hours I use in this class coming out of the hours I purchased or will I be credited back the hours I using for this workshop? Thanks, Christopher ---

Hi Christopher, your account should be updated to 1000 core hours. When did you register for the workshop? If there are still any problems please send me an email ([mmafi@simscale.com](mailto:mmafi@simscale.com)) Cheers, Milad ---

Hi @anon67859130 , am I allowed to run multiple simulations simultaneously? Like running 525,1050, 1575 and 2100 rad/s at the same time. Just curious. Did not try it so far but just wanted to know for later on. Thanks, Jousef ---

Jousef my Friend 🙂 For sure you are allowed to run multiple simulations simultaneously! That’s by the way one of the big benefits of using SimScale. Unlimited computing ressourced whenever you need them 😄 Have a nice weekend! Cheers, Milad ---

Thank you @anon67859130 😄 Tried it 2 hours ago. Awesome feature! Have a nice weekend too! Cheers, Jousef ---

Hi @nikuradse , refering to your post u did about your forces ([https://www.simscale.com/forum/t/step-by-step-tutorial-homework-of-session-1-level-1/297/2](https://www.simscale.com/forum/t/step-by-step-tutorial-homework-of-session-1-level-1/297/2)) I will show you my results. P.S.: Maybe you can share your link with the community then I will have a look at it.

Are there any experimental results available for validating the results we are getting through this simulation? ---

Hello Gurav, not for this case but we made a lot of validation projects in the past. My colleague @Ali_Arafat made for example a simulation of a valve with the same solver (OpenFOAM) which was validated with experimental results. It is really amazing: [https://www.simscale.com/blog/2015/09/validation-case-highlights-butterfly-valve/](https://www.simscale.com/blog/2015/09/validation-case-highlights-butterfly-valve/) Cheers, Milad ---

While doing task 2 meshing, I am getting messages in event log like - “Illegal triangles were found…”, “The tesselated surface is not closed…” Will this affect the mesh quality? ---

Hey @gurav_harsh , did you try meshing it a second time? Because I did not get any errors while meshing. Maybe give it another try and see what it does. Good luck! Jousef ---

Hi @jousefm Here’s the public link to that project: [https://platform.simscale.com/?publiclink=b30ef4be-6014-4481-88b3-c64fd57ee87d](https://platform.simscale.com/?publiclink=b30ef4be-6014-4481-88b3-c64fd57ee87d) It has three simulations as I thought that it may vary with the iteration but it didn’t. I have just read from @anon67859130 that it may be an issue with the boundary conditions so i’ll check them out again and the whole thing as well. Thanks a lot for the help!
