" Found equation without time-dependent variables: R1.a.Q=0.0"

When i try to simulate my model, this message comes up: " Found equation without time-dependent variables: R1.a.Q = 0.0", and i am advised to take a look at my connector, but i can't understand what's the problem.
There is also another message that follows:" Model is structurally singular, error found sorting equations ".
Do anyone have any idea about what is wrong ?

Hi,

I am encountering this same error. I am trying to simulate a fluid (valve) system and am getting the following error:

Code:


[3] 12:04:41 Symbolic Error
[Modelica.Fluid.Interfaces: 13:5-14:68]: Found equation without time-dependent variables: port_a.m_flow = 0.0

What does this error mean and how, generally speaking, do you resolve the issue? Thanks.
