Water Hammer Arrester Simulation

Good Evening Guys.

I got a water hammer project. There seemed a problem. This software found an error while the solve applied. The error notification: Dissimilar Fluids (Two different fluid parts are touching. Check material assignment to ensure that all contacting fluid parts are assigned the same fluid material).

I ensure that there are no touching two fluid parts. To inform you this problem, I attach the print screen.

May you can solve this problem. Thank you for the attention. 130506.jpg

Do you have water and air touching? If so, that will explain the error, as you cannot do this 🙂

No, there was no touching air and water.

Hi @hbaroki,

 

Perhaps you can remove and then reapply your material properties? Then check if you get this error message again. Feel free to attach your support file (.cfz) here. I am happy to take a look at your model. 

 

Thanks,

Hi @hbaroki,

 

I had a look at your CFD project and it looks like you are no longer facing the issue of two different fluids touching. I opened your project and hit solve and the model worked without issue. I suspect either you removed and then reapplied the materials or maybe changed the setup a bit in CAD.

 

Glad to see your project will solve now.

 

Thanks,
