How to advance on Task 3 of "Multidomain Modeling The Fluid Domain" in Simscape Onramp?

Hello, I have done everything that is indicated for task 3 (Multidomain ModelingThe Fluid Domain) in Simscape Onramp, but the training assesment panel indicates my plot is wrong. I have checked everything several times and started over again the whole task, but still don't get the plot indicated on the training assesment panel. Any suggestions please?

Same issue, any help would be appreciated

[Alexandra Murphy]

I am also having the same issue.

[Talha Enes Ercan]

I'm also getting the same issue.

[Jorge Ponce]

me too, same issue

[Rodrigo Gil Marin]

In the Liquid Properties block, please change the value for 'Volumetric fraction of entrained ...' to zero. This should allow you to move forward with the training

[Jose Espinosa]

Thanks Rodrigo, it worked. I wasn't aware of that air property.

Thank you!

[James Lagroue]

Excuse me but I can’t find anything like that in the block parameters of pipe (il). Where are you seeing this?

[Philipp Heinle]

Hello, I have the same problem.

[Peter Dittrich]

Holly moly, I advanced in the online version to this point in order to notice that this problem does not only occur on Desktop.

Thanks Rodrigo, setting the 'Volumetric fraction of entrained air in the mixture at atmospheric pressure' to zero helped!!

[Thomas Engleder]

Thanks - same problem. Is working now.

[Durgeshwar Sahu]

same here.

[Dennis Kachila]

wow!! thank you for that i have stuck here for so long tried everythong too..

The solution worked properly with the given answer.

[Sarmad Doulan]

Hi Rodrigo, I have the same exact issue. However, when I changed the Volumetric fraction of entrained ...' to zero, it didn't solve the issue. Anythoughts?

[Ruoyu Dai]

Thanks so much Rodrigo. You saved me.

[Erin McKindles]

Thank you thank you thank you!! You are a life saver!

[Thameenansari S]

thank you so much

[KUNAL THAKKAR]

Thanks Man, but how did u figured that out ?

[Haytham Eladam]

Thanks man, but really how did you know ?

[Alisha Schor]

This is related to a change in the default parameter value for that block: https://www.mathworks.com/help/physmod/simscape/release-notes.html?rntext=isothermal+liquid&startrelease=R2019a&endrelease=R2022a&groupby=release&sortby=descending&searchHighlight=isothermal+liquid

"To improve simulation robustness, the default amount of entrained air for the isothermal liquid domain has been changed from 0 to 0.005."

The course will be updated in a future release to not require this workaround. Thank you for your help, Rodrigo!
