Which software is good for PV cell-to-module simulations?

I have the solar ray tracing data falling on a 3-D body in the form of x, y, and z coordinates. The fourth variable is the watts-per-ray data. I need to convert this data to a 3D pixel map so that I can convert the x,y,z (watts) data to x,y,z (watts/m^2) data based on the number of pixels assigned. How can this be done? Is there any specific tool to do this?

How to understand the concept of Mesh Orientations on Solar calculator. Is there any research article or video please share it.

Hello fellow researchers,

I recently started learning how to use SolTrace and have been struggling with exporting the heat flux data from SolTrace. I am aware that we are able to see the flux density under the "flux maps" tab. However, under the "Data" tab I only see columns of data for pos x,y,z and cos x,y,z, element, stage, and ray (a total of 9 columns) and no Flux density data.

I believe I am missing something here, maybe there is some calculations I need to do for these data to find the heat flux but I am not sure how to move from there. I would appreciate it if I can get some guidance on how to export or calculate the heat flux values from SolTrace.

Thank you for your attention!

Hello,

I've recently been trying to run a transient simulation of a system with Fluent's solar ray tracing. I've been running into issues as to get proper results I need the simulation to go on for more than 48 hours. For some reason, after the first 24 hours of a Fluent simulation, the sun doesn't rise again. That is, from the 24th-hour onwards, solar flux is always 0. If anyone knows how to fix this let me know.

I understand that it should be possible to use a piece of software such as SolTrace to get the solar boundary conditions and then apply these to my transient simulations. Unfortunately, I cannot understand how to do this at all and I can't find any guidance online. I'm relatively new to Fluent so if someone could point me to a helpful source or give me an explanation I would be very grateful.

I'm also open to other solutions if people have had similar problems.

Thanks!

Hello,

I am running a simulation of a system powered purely by energy from the sun. During the daytime, the results are as expected. During the night, I expect the system to still have a large amount of motion as there should be a decent amount of heat stored in the system. However, whenever I try to run a simulation spanning 24hr, I get a floating-point error when the sun sets. Before the error, I get some anomalous data where the temperatures and velocities are way too high (out by 4 orders of magnitude or more). I really don't understand what the issue is here. When the sun sets shouldn't the solar loading just stop? Shouldn't the system just slowly use up its remaining energy until the sun rises again? Is it possible that the radiation is falling on the base of my geometry?

I think that I am misunderstanding something about the solar loading as it is this that triggers the issue. In my attempt to troubleshoot, I set up a system that was definitely stable and well defined without the solar load. Then, when a solar load was applied and I ran it in a 24hr transient simulation I faced the same issue.

Any help, advice, or a point in the right direction would be appreciated.

I mean whether articles under review can be added to the resume or not.

Please I am working on simulation of solar still I wanted to add a solar radiation so I used solar loading and used solar ray tracing and used solar calculator to define my sun direction vector instead of entering it manually and my problem is that the sun rays seems to be under the solar still not above it so I want to learn If anyone knows how to probably define the sun direction vector from a certain correlation or from the solar calculator it seems I doesn't understand the mesh orientation how to define it

Thanks

Need to create 3d surface plot. Data I have X, Y ,Z coordinate of the pipe surface and the corresponding Q (heat flux) values at that point. Nearly 222440 data points of a 2m length pipe.

Thank you

What is the suitable and acceptable error variations between the CFD results and experimental data?
