But if the block (B1) x_min value is set to -7.51 (from -7.5), it fails.
I have tried smaller grid sizes. I tried specifying grid size for each subdomain. What about reorienting the objects?
The wire dimensions are very small compared to 10m. 0.5mm radius. So that's a ratio of 10/.0005 = 2e4... Does this ratio (largest dimension to smallest dimension) have a practical limit? Could some FEATool tolerance be changed by the user that might allow a greater difference (at some processing cost, no doubt).
Unlike some of my models which turn out to be exploratory/learning tools, this one is tied to a specific geometry and experiment hat I want to replicate.
Any hints as to how to go about finding the problem and/or how to solve it would greatly appreciated.
This message indicates that there has been an error in the decomposition of the geometry into minimal and non-overlapping domains. This should be equivalent to getting the intersection of OBJ1 and OBJ2, and OBJ1-OBJ2, as well as OBJ2-OBJ1 (if you manually create the minimal regions and it might work). I'm guessing the issue is the scale difference that the geometry engine can't handle well, I will try to have a look when I can but I'm not sure there is an easy fix. High aspect ratio/scale differences is unfortunately always very hard for these types of simulations, geometry, grid generation, as well as solvers.
