      スキューが悪いメッシュでの熱計算の場合の収束性改善方法として、Heat Flux の２次勾配を無視するコマンドを使用することがあります。 この際全ての領域で2次勾配を無視したい場合に、『１．全領域』入力すると『２．wallのみ』は入力する必要はありません。 但し、shell conductionに関しては『３．shell conduction』を別途入力する必要がありますのでご注意下さい。 1．全領域 　　 (rpsetvar ‘temperature/secondary-gradient? #f) ２．wall のみ 　　 /solve/set/expert/use-alternate-formulation-for-wall-temperature? yes ３．shell conduction のみ 　　 (rpsetvar ‘temperature/shell-secondary-gradient? #f) ※ ()括弧も含めて入力する
