FAQs on Drone Simulation

I just tried to start my webseminar. But I am getting this message…
This webinar is not open yet to attendees. Please come back at the scheduled time below.

also, where can i download the GoToWebseminar.exe file?
Please reply ASAP.

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,


Hi @jousefm and @Milad_Mafi,

Where can I find the recorded webinars. I missed the second half of today’s session.
Looking forward to the other sessions !!!


Good evening @asonar ,

the webinar will be uploaded tomorrow morning. Patience is everything mate :sunglasses:


@jousefm, thanks.


Yes, I missed it.
I live in India.
Where can I find recordings?

I tried to do level 1, but getting error - The machine ran out of memory. Please choose a larger machine for computation.

My system is of 4 GB RAM.

Hey gurav,

as mentioned in the step-by-step tutorial you have to choose a larger number of computing cores.

You can change this under Simulation Control



Hey Guys,

the recording will be available around 12:30

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?


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)



Hi @Milad_Mafi ,

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.



Jousef my Friend :slight_smile:

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 :smile:

Have a nice weekend!

Thank you @Milad_Mafi :smile:

Tried it 2 hours ago. Awesome feature!

Have a nice weekend too!

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) 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.

Cheers mate!

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:




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!


Hi @jousefm

Here’s the public link to that project: 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 @Milad_Mafi 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!
