  こんにちは、平面波が障害物を通過するときの音圧分布を解析で導き出したいのですが、下の画像に示すように、実際の定数に関するエラーメッセージが表示されます。
  この問題を解決する方法を教えてください。

  I suggest also to use coupled field harmonic where we can do very easy 2D acoustic analysis in 2024 R2 (fluid243/fluid244 – new elements).
  In the course/example here we have also a 2D example which you can follow.

  All the best
