I want to change the reference pressure value from 1.0e+05 Pa to 0 Pa when I run a model,in the "monitoring and reference data" I tried to change the reference pressure value into 0 Pa,but when I typed the "apply" buton,I found the reference pressure data value always to return to 1.0e+05 Pa.

So,I want to know whether I can change the reference pressure value,if possible,how can I do?

Thank you very much for your help!

This is probably a design erro - but as a fix, you can use a very small non-zero value such as 1.e-05

The thing is, the reference pressure value needs to be input as absolute pressure and if you set it to 0, you basically specify perfect vacuum; hardly a condition where the Navier-Stokes equations apply anymore... Perhaps CD have put a limit on purpose?

Regs,
