There are many loads on a building for cooling or heating requirements. These loads are transmission or conduction, solar transmission, solar, occupants, electrical appliance and lights (called as internal heat gain).

Test centre is available in my city so i should prefer at center or at home?
At test center is preferable in this case.
So is Ti equal to your HDD or CDD value?
No, HDD and CDD is number of hours or days for heating and cooling respectively. Ti is indoor temperature.

I saw your previous vedios sir those are very helpful kindly help to resolve my issue of creating structured mesh.
Hey, I have already replied to your previous comment. Please mail me some details and we can connect on zoom to sort out the issue.
Sir I have mailed you all details kindly check.
Sir i am also working on cfd simulation and facing issue in creating structured mesh. Kindly help to create structured mesh in fluent. It would be great help
Hey, I have already replied to your previous comment. Please mail me some details and we can connect on zoom to sort out the issue.
Sir I have mailed you my geometry file kindly provide suitable time to create structured mesh. It would be a great support sir . 🙏🙏🙏🙏🙏
Sir I am also working on cfd ( Persuing PhD from NIT patna). I am facing issue in generating structured mesh in my geometry can you help me in resolving issue.it would be great help sir.
Hey, Sure, I can try to help you in generating better mesh. It would be great if you can share some screen shots of your model and the current mesh you have generated. You can directly mail me on dhyan3patel@gmail.com
Sir I have mailed you my geometry and meshing file kindly check
So for multifamily buildings that have separate units with their own heating/cooling systems, would each unit be its own zone?

Hello sir! I have a hexahedral multi-block structured mesh in ICEM CFD, I got some results from this mesh. Now, I have to do a mesh independence test. Please tell me which is the correct way to increase the number of mesh elements: Should I 1) Re-mesh the whole geometry with smaller element size 2) increase the number of nodes in each block. 3) increase the scale factor like 1.2 or 1.3 etc.... Thank you!
Hey, Thanks for reaching out. Without much details about the geometry, it is difficult to give any clear suggestion. However, in general I would try to increase nodes/elements in areas where there is more stress, bending, etc. I can use a sphere of required radius and assign a smaller element size in that sphere. And use that sphere in all such locations where I expect more stress. I hope that is useful. Else I would suggest to send me some clear screen shots of your geometry and current mesh on my email.

Sir I don’t understand that the exam centre is where and how to apply for exam centre
You need to go to ETS website, and setup your account, register yourself for the test, make the payment. Then you have the choice to select exam date and location. There would be a video related to that regarding GRE.
how can we paramterize diameter of a circle? Please answer, I am unable to do that. Thank you.
I hope you have created the geometry using a script as shown in this video. For the circle, when you select to make circle using the button on top menu, there would be options to define circle using different parameters such as 3 points on circle, center and diameter, center and a point on circle, etc. These are different ways to define circle and when you select center and diameter as two parameters, then you can get these two parameters. I hope you got the answer.
wait are you writing backwards?
Not actually! Great that you noticed! Actually the captured video is flipped with y-axis so I filled again and so it looks writing backward.
THANKS. VALUABLE INFORMATION
Welcome!
nice
Thanks!
Thank you! What formulas would you use for Beta in other types of control charts (c, u, p, np, etc.)?
Great question! I haven't touched this things in a while now. From my distant memory, I think there were ways to convert one type of probabilistic distribution to normal distribution and then standard normal distribution. In that way, the given formula will be useful. Otherwise, you can always use the theoretical definition of probability below and above the control limits in any distribution and take their sum to get beta. Hope you got some idea. Let me know if not.
@@dhyanpatelbitspilanitotamu1520 thank you. I believe c and u use Poisson distributions and Beta can be found by using a cumulative poisson formula. Still need some more details on that front, but I appreciate it!
If you can find more info on this, I would be highly appreciative. Thank you!
@@lucastyler5549 Sure!
How can we decide about mesh quality while looking at more than one quality parameter, if element quality is good but skewness is bad what will we do ?
I use to primarily look at element quality. If my element type and size (at corners and thin layers specifically) is correctly defined at the first step, then only element quality is enough.
@@dhyanpatelbitspilanitotamu1520 Thank you so much what is the "criterion for correct element size and type
@@okhwatnoornoor8893 Usually I looked at thin parts in my model. In general, I would try to keep 3 elements across the thin section. And if there are multiple bodies in a model, I would use larger size elements in other area.
I believe looking at other videos in this playlist on Meshing will give you some idea. And you can also check one of my interaction videos (3 total) where we did live recording while meshing a body.
thanks
Is there a possibility to modify meshing without modify the geometry of the L shape control arm?
Yeah sure, you can modify mesh without modifying geometry, but if you modify geometry, you will have generate mesh again.
Mesh is on the geometry, so mesh can be changed anytime without changing geometry. But if you change geometry on which mesh was earlier generated, you need to make the mesh again.

If I have to apply for more than one university abroad how they will do it
Hey, The letter of recommendation needs to be sent to each university separately. I hope you were asking this. If not, please clarify your question for me.
My question, is nowadays abroad university asking for a professor mail id and their names to send direct links, asking them to summit the recommendations. Is it possible for 2 professors to edit the name of University each time in Lor and then summit to the link for a student.
Yes@@reyan9124 . I would suggest to not include the name of university in the letter. Just writing 'your university' is fine. That way professor does not need to make any change in the letter.
Please reply one more thing regarding SOP.I study in the "ABC institute of technology" which is affiliated with "xyz University". Now my bachelor degree is in the name of "xyz University" and the university mentioned on the degree that he was a student of ABC institute of technology. How should I mention it in the SOP?? Another thing is I have a gap of 4 years after bachelors, should I mention it in SOP. that I was preparing for a govt job.... Please reply it will be very helpful.
