Very informative session, May I know sir which comsol version u r using.

[@pioneerofsuccess4054]

Any version of COMSOL would suffice.

Have u noticed that colour scheme changed when u imported it inside comsol.

[@pioneerofsuccess4054]

Yes, I did notice. I will think about the reason and let you know. You can also write to me if you have the answer.

@@pioneerofsuccess4054 that's because the image scaling option is showing the average of three colours per pixel ( r+g+b)/3, if u write only ' r ' ( portions with red content will get higher values) and so on.
To revert it back to its original colour, some calculations needed ( 0-255 , three 8-bit colour channels and picture L x W pixels)
Got this info from COMSOL ref. manual.
I want the image fn show true colour, whole last week, trying to figure that out 😀
still trying.......

@@atanughosh8312 Actually, color images bear three different variables. When we are using them we are using as a single valued function and that is why we need to merge three variables into one. Anyway, excellent observation with accurate explanation. I thank you.

Hello Sir,
Thanks for the explanation. Very nice and knowledgable vedio.
Can you pls let us know how we set x and y axis (scale)?
