XsimのサイトのテンプレートはFOUNDATION版のため
ESI版のOpenFOAMに設定しなおす方法を紹介します。
OpenFOAMv7でエクスポート後ControlDictを編集します。
system/controlDictを編集します。
・FoamFIleにlocation "system"を追加。
・writeCompression をoffに変更。
・#includeFunc residuals(U,p,k,epsilon);を//でコメントアウト

Ubuntu20.04 OpenFOAM-V2006で残差を確認するには
plotという名前で以下の内容のファイルを作成します。
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
#!/usr/bin/gnuplot -persist
set title 'Residuals'
set xlabel 'Step'
set ylabel 'Initial residual'
set logscale y
set format y "%.0e"
set grid
plot 'logs/Ux_0' title 'Ux' w l
replot 'logs/Uy_0' title 'Uy' w l
replot 'logs/Uz_0' title 'Uz' w l
replot 'logs/p_0' title 'p' w l
replot 'logs/p_rgh_0' title 'p_rgh' w l

foamJobでソルバー実行時に(例えばfoamJob simpleFoam)
foamLog log
./plot
とコマンドを入力すれば残差がグラフで確認できます。
（gnuplotがインストールされていることが前提）
