Creating custom Simscape components in two-phase fluid domain

Flow resistance simscape component in two-phase fluid domain uses function <foundation.two_phase_fluid.normalized_internal_energy> - see below. Where I can find this and other two-phase fluid domain functions for building custom simscape blocks?

Thank you in advance,

% Normalized internal energy for inflow

unorm_A_in = foundation.two_phase_fluid.normalized_internal_energy(A.u, p_A, ...

A.u_min, A.u_max, A.p_TLU, A.u_sat_liq_TLU, A.u_sat_vap_TLU);

unorm_B_in = foundation.two_phase_fluid.normalized_internal_energy(B.u, p_B, ...

A.u_min, A.u_max, A.p_TLU, A.u_sat_liq_TLU, A.u_sat_vap_TLU);

This only works for the functions in the Simscape foundation library.

Select the full name of the function, right click and select "Open xxxxx" or Ctrl+D

Now you opened that code, you can open the folder where the code is located:

In that folder, if you see any .ssc file that doesn't look like a Simscape block, well, it's probably an internal function used by other Simscape blocks. You can also search for .ssc and .m files in that folder, look for ones that are not a Simscape block in the library.

Please note that these functions you may find, they are intended to be "internal". Documentation is minimal. No guarantee that future versions will have the same functions or the same inputs/outputs. So, proceed with caution.
