two-phase fluid Simulink

Hi,

I am having some troubles simulating a hydraulic model with a two-phase fluid in Simulink (using Simscape Fluids)

The model works properly when the inputs in the "Two-Phase Fluid Properties (2P)" block are defined within the subcritical region (Pcritical = 46 bar in my model). However, when I extend the pressure vector (and the other thermophysical properties of the fluid) over the critical pressure specified in the block, the following error pops up:

Error compiling Simscape network for model aaaa.

Caused by:

• ['model/block': In foundation.two_phase_fluid.utilities.two_phase_fluid_properties (line 898)

The bold equation below seems to be popping up the error message:

if n_sub < n

assert(all(v_sat_liq_sup(:) == v_sat_vap_sup(:)))

assert(all(s_sat_liq_sup(:) == s_sat_vap_sup(:)))

assert(all(T_sat_liq_sup(:) == T_sat_vap_sup(:)))

assert(all(nu_sat_liq_sup(:) == nu_sat_vap_sup(:)))

assert(all(k_sat_liq_sup(:) == k_sat_vap_sup(:)))

assert(all(Pr_sat_liq_sup(:) == Pr_sat_vap_sup(:)))

I have defined the liquid and vapor-saturated curves over the critical pressure to be exactly the same but still getting that error...

Anybody had similar problems? I Would appreciate any comment/hint with this.

Thanks!

Alejandro.
