{Version I am using: ls-dyna_smp_d_R13.1.1_27-g8731a0d8c5_winx64_ifort190.exe} (_d_, double precision, so I don't think there is an error source from precision.)
Furthermore, I had stumbled upon a post and tried to change the “NUMLS” in em_control, from 100 (of the exemplar), to 1000. Which, this solves the issue with the FEM-BEM failing to converge, which I don’t understand why. And as seen in the image below, it says that NUMLS should only be in effect when “EMSOL” == 2, which in my case “EMSOL” == 1, as I am using the Eddy Current Solver. Regardless, as seen in image below below, a different type of error is outputted. And when I try to view my calculated d3plot file, the result makes absolutely no sense, this applies for both the exemplar file and my personal .k file, in the sense that their result makes no sense once “NUMLS” is changed to 1000, which is weird it’s even taking effect in the first place.
This is likely irrelevant, but just an interesting detail that I noticed. But to be honest, I just don’t really understand why is the FEM/BEM failing to converge, because my mesh shouldn’t really be erroneous? You can also refer to the source of the .STEP file in my Github repository: https://github.com/Ice-Citron/FEA-Physics_IA/blob/main/src%20STEP%20file/Square%20Augmented%20-%20Further%20Splitted.step
I hope someone can help me out of this, as I am out of options now, both solution and time, as I had spent a lot of time on this and my deadlines are coming up for my Physics Coursework. You will have my deepest gratitude. Thank you.
