in simscape fluids, I want to use the gas-charged accumulator, which is a single phase component, in a 2 phase loop. How can I use it?

I am simulating a cooling loop for a bech top setup and I have a gas charged accumulator in the setup. I want to use the block gas-charged accumulato which is available in Fluids-Thermal Liquids on a 2 phase model. i am not able to ad this because they are not compatable. Is there a way to do it. I thought of creating a block from the source code but its not available.

Try something like this:
Use Translational Mechanical Converter for each domain, connect the R port, and add a small mass. Reverse the orientation in the dialog box for the gas one (IMPORTANT!!). That's pretty much a gas charged accumulator. The two fluid chambers will almost always have the same pressure. If you would like to the temperature to be linked as well, you may connect the H ports via a small thermal resistance. You can add a spring and/damper to the R port if your component has one.
