Hello everyone,
I am analysing a chemical reactor. I am confused with compressible ,incompressible and weakly compressible gas, and in which occation they are used. My simlation is for high pressure.I do not know how to set reference pressure, their relation with absolute pressure and how to use it for compressible incompressible and weakly compressible gas. I am in urgent need for your help. Thanks a lot for your help.
Best regards,

这个，不知道你的版本是4还是5
在5里面，好像是有这个选项的，
4的fc文件里面也可以设定，不过我也没有用过，
要想好好的用，只有去查手册了，
那个是最好的师傅。
