The reporter tested this open PCB impedance solver with a headless runner on unmodified source. Points inside conductors get permittivity 1, putting a thin air skin around every trace; a homogeneous stripline at 4.1 reads an effective permittivity of 3.88 on a 4 um grid and 3.71 on 8 um. Microstrip reads 1.7 to 4.9 percent low depending on Gauss contour distance, a 20 um solder mask case reads up to 10.8 percent high, and a trace under 0.1 mm of dielectric reads 7.9 percent high.
Recurring agent failure issue in RF2DFieldSolver (jankae)
What engineers report
A recurring agent failure problem in RF2DFieldSolver (jankae) that mostly hits the electrical engineer.
Failure pattern: validation / failure
Analyst note
From the Grok pain-radar digests, Nov 10-11 2026 (Nov 10 8:41 AM ET through Nov 11 7:41 AM ET digests plus the Haitch editions). Verified live 2026-11-11: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost
240 min
Per engineer per month, about 1 incidents
How the cost is modeled
240 min/month × 5 engineers × 12 months = 240 hours × $125/hour = $30,000
A modeled estimate with medium confidence. Swap in your own team size and loaded rate to size it for your team.
