      incompressible ideal gasは、理想気体の状態方程式の圧力値にOperating Pressureがそのまま使われるため、Operating Pressureを0[Pa]にすると密度も0[kg/m^3]となってしまいます。（0Paに設定するとWarningが出ます。） incompressible ideal gasを使っている場合は、Operating Pressureが0Paにできないため、境界条件を絶対圧で指定できません。基準圧をOperating Pressureに設定して、その値との差として境界圧力を入力して頂く必要があります。 関連マニュアル https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v194/flu_ug/flu_ug_sec_density_incompress_ideal.html
