FAQ
ParticipantExpressionでは境界条件等を物理量の関数で与えることができますが、物理量の累乗を含める場合、0.333などの小数を累乗にするとエラーが出る場合があります。 このような場合は、圧力であれば1[Pa]、温度であれば1「K]で割ることによって無次元化することでエラーが回避可能です。 例: (WallTemperature-288.16[K])**0.333 や (WallTemperature-288.16[K])^0.333 でエラーになる場合 ((WallTemperature-288.16[K])/1[K])**0.333 や ((WallTemperature-288.16[K])/1[K])^0.333 とすると、物理量の小数乗ではなく値の小数乗になりますのでエラーが回避されます。
