Hello Sir, very good video. I want to know, how to know the function like what will it be, and for what parameter we need to write a function... Please explain. Thank you.
Thank you for you comment. The mathematical functions that we use in comsol modeling are taken from literature and even you can define your own function if you know the problem statement entirely. It can be a contnious or piecewise function depending on the problem and the type parameters depend on the type of study you want to solve, it can be stationary or time-dependent.
Hello, Can you please help me with a cfd simulation similar to this? I want to simulate gas flow in a cylindrical chamber using transport dilute/concentrated species . I have mostly done it but there are few parameters I do not understand. Can you please help me with this? I need to understand the mixing/diffusion and time taken for the gases to fill in the chamber. Please help.
Amazing, thanks.
Glad you liked it!
Great!
Thanks.

Hi cool video. I want to simulate the same but with the natural gas. What should i do ?
Thanks in advance
thank you sir
Most welcome
Sir can you please tell me from which research paper or article I can find the velocity function which you have mentioned in this video.

Hi,
Please share you comsol model and problem details on the following email address:

Hi, how did you solve your problem!? Now i faced the same issue ))
do we have to set analytic in parameter as in my case it is showing undefined variable
Yes, please pause the video and insert those parameters in your model. Alternatively, I will share the file of parameters soon.
Can you tell the dimensional form equation of the following dimensionless equation 1.5*(1-(4*y^2))
لقد عملت نفس الخطوات ولكن خزان مياة مع انابيب
ولكن تعامل مع جميع الاسطح حوالي 40 سطح
هل يمكن أن توضح لنا المشكلة التي تواجهك في المحاكاة بالتفصيل؟ سيكون من الأفضل أن تنشر سؤالك باللغة الإنجليزية.
can you please write the velocity function here? the video is really blurry and i don't have speakers on this computer. thank you
5*sin(pi*t/4)
Sir can you please tell me from which research paper or article I can find the velocity function which you have mentioned in this video.
Is there a way to get flow rate?
Yes, you can calculate the flow rate by multiplying the velocity field function with the area (dx*dy).
