Wrong volume and level from tank (TL)

Hello

I am modelling hot oil system in simscape where expansion tank is modelled as Tank (TL).

I have specified maximum volume as 5.6 m^3 but when I run the simulation, I get the volume of fluid in the tank more than 5.6 m3. why is it so?

why is it so?

How can we know this from the information you gave us ? Is there no warning that the fluid volume exceeds the tank volume ? Maybe using a smaller time step and/or higher precision can help.

Hi @Muhammad Ali,

As @Torsten mentioned, it's impossible to diagnose based on the information you provided.

It seems that you initialize the tank with 0.8m^3 of liquid volume, which is indeed the starting point of your simulation. Then the volume increases, which I believe is a result of some inflow through one or more of the four ports. You block is set up with a warning, instead of an error, when the volume exceed maximum, so the simulation will go on with a warning message. Did you get that message?

It'll help the community to understand your issues if you can attach your model and explain what the intended behavior should be.
