Hi I am trying to perform FEA on a solar panel. Basically I am trying to assign material to the structures. I want to select galvanised iron for its structure but I am unable to select it. I only have the option of iron. Can anyone help me how can I change the material properties of iron to galvanis…

In your case I used HEX mesh as it was easier to me to control the mesh fineness and limit overall cells count (by applying region refinement near the geometry and keeping cells big in far field). One can now use TET mesh, by defining an enclosure, but a lot of different setups should be used to a…

ok no issues @BenLewis . thanks alot

@Retsam one more thing I would like to ask was that the CFD analysis which you did for my project was based on a wind angle of attack of 180 degrees right ? I would also like to ask that if I wish to change my angle of attack , how would I be able to incorporate that effect in my CFD analysis ? I me…

@BenLewis one more thing that I wanted to ask was that would we have to add welded joints between the I beams while performing FEA ?

Hi @alijalil , For different flow angles, you need to do the following: For changing the wind direction from Front to Rear, you need to rotate your geometry by 180 degree (as an example) . That rotation should be done in your CAD program. You need to import again the geometry into SimScale and recr…

Hi @alijalil , I’m SimScale you can assess the weld strength by modelling the weld geometry. The means separating the members by a small amount and joining them only at the weld interfaces. This can be a time consuming job, so you want to avoid it if possible. Here are some points to keep in mind: …

one more thing @Retsam . was there any particular reason for selecting hexa dominant parametric type of meshing for the CFD analysis? Secondly was there any reason for selecting surface refinement and region refinement both ? Couldnt we use only surface refinement and only region refinement ?

Hi @BenLewis ! Please can you send me its CAD model ? You sent me this picture a few months ago. It would be highly appreciable if you send me its CAD model as well. You can email me on the following email address: mohammadalijalil48@gmail.com [image]

Hi @Retsam . Please can you help me out with the CFD analysis of the following structure. I’ve performed CFD however the results seem to be non physical. So please can you help me out with this. Also please can you help me with the force and moment plots. How should I get the value of forces. …
