Can we perform manual ray tracing for the central receiver solar power system

Sir, thsnks for the video, in my version of software dont have the icon of flux analysis, do you know why? Thanks so much for the support, gratting from Mexico

Thankyou🎉

Hi sir, thank you very much for your help using this software, it helped a lot. I want to find out how we could get the circumferential distance vs the heat flux on the object. You did for surfaces where you ''Run Flux analysis''. Any form of assistance on this would be appreciated as well.

Thank you very much. Can you please make a video on how to import the file into ANSYS for the non uniform boundary condition?

sir can u please share ua contact no?

Sorry sir, how we know total irradiance in receiver?

hello, very informative video. can you pls tell me how can I rotate a cpc geometry form N-S orientation to E-W orientation ? Directly changing from (0 0 1 0) to (1 0 0 0) does not work in tonatiuh.

Sir For surface node is not created in heat flux generation can you please help me

sir can you please flat plate compounded parabolic cocentrator how to calculate heat flux and ray tracing

i tried to use elliptical shape of receiver by importing the CAD shape but when i tried to analyze the flux it says the surface node is missing. But i had already created the surface node to import the geometry. So can you help me related to this... the ray trace formation occurs but flux analysis is not working for imported CAD geometry

u are soo good, thank u for help!

Can you explain how to get absorber circumferential angle Vs heat flux plot from contour or surface plot (variation with x, y coordinate of heat flux) obtained in soltrace or tonatiuh for absorber tube of parabolic trough collector

Can you explain? How to get absorber circumferential angle Vs heat flux distribution plot from contour or surface plot generated in soltrace or tonatiuh.

I have one more question. Should I use the same code if I am smulating linear frensel collector with horizontal receiver

can you plz send me the google drive link because the one in the description not working, thank you so much for so much. your videos helped me a lot in my bachelor thesis.

sir pls send ur email id

Hi, thank you for this tutorial what if the receiver is not a flat disk, how can we change the code accordingly

I installed latest version of the software but after importing the 3D shape, software shows either 2D shape or changed shape of original 3D. Please Help...

hi, I found your video very helpful. I was not able to access txt file from this google drive. I would really appreciate it if you could share it. I was running into some errors while running the code mentioned on GitHub tutorials

Can u place a video on LFR SOLAR RAY tracking using tonatiuh

Thank you very much for this!

Hi, I installed tonatiuh but it does not show me CAD shape to import geometry please help me ... thank you in advance

Hello, Please let me know when you will be posting the post processing video!

Hello, could you please help me with post-processing/ obtaining results from Tonatiuh software? Please share your mail Id or mail me at [email protected]. Thank you for your time.

How can we post-process this .dat file to get results such as Total power at absorber, etc?
