お世話になっております.
上記の手順で粒子の計算を行おうとしていますが、最初の段階でつまづいてしまいうまくいっておりません。
・mapFieldsを使用すると以下のように実行できましたが、paraviewで確認しても流れ場が表示できませんでした。なぜ表示できないのかわかる方がいましたら教えていただきたいです。

--> FOAM FATAL ERROR: (openfoam-2206)
Could not find U: U or p:p in database
From void Foam::functionObjects::forces::initialise()
in file forces/forces.C at line 172.
FOAM exiting
これはどこのファイルにp,Uが見当たらないエラーなのでしょうか。
ご教授いただけると幸いです。
よろしくお願いいたします。
