| Symptom | Likely fix | |---------|-------------| | FDTD diverging | Increase mesh, reduce time step, check material fitler | | CHARGE not converging | Increase iteration limit, refine mesh at junction, check BCs | | Monitor data looks NaN | Run with smooth mesh off, check geometry overlap | | INTERCONNECT error | Check element names for spaces, rebuild netlists | | Script error “unexpected symbol” | Verify Lua syntax – use ? command in script prompt |

FDTD, photonic crystal, optimization

Hi everyone,

: Do not upload a massive, multi-gigabyte project file. Create a minimal working example (MWE) that reproduces the error in a fraction of the time.

Then came Jun, who liked to build toys for the forum—small, downloadable project files that users could run to reproduce a problem. Jun uploaded a compact test case and annotated each line: "This one isolates the reflection from your boundary conditions." Ari downloaded it, eyes scanning the annotated comments as if they were a map.

The forum is an official, moderated space where users interact with peers and expert Ansys engineers. It functions simultaneously as an interactive troubleshooting board, an archive of legacy physics solutions, and a collaborative workspace. command in script prompt | FDTD, photonic crystal,
