please help regarding temperature measure of a electrical network

The model may not give enough information to make it possible to solve for values of some of its variables. Specific advice is given below.

all components and nodal across variables involved

Cannot solve for one or more variables:

'DC_Current_Source.n.v' (Voltage)

'DC_Current_Source.p.v' (Voltage)

'Resistor.n.v' (Voltage)

'Resistor.p.v' (Voltage)

'Thermal_Resistor.n.v' (Voltage)

'Thermal_Resistor.p.v' (Voltage)

Dependency found among topology equations. Check for missing reference node.

Component: Simulink | Category: Model warning

An error occurred while running the simulation and the simulation was terminated

Caused by:

['temperaturesensor/Solver Configuration']: Failed to update switched linear model, due to system singularity in current configuration.

Error Simulink is thorwing indicates that the solver does not have enough information to solve the equations. Add an electrical refrence to the circuit as ground in the netowork to allevaite this error and check all the parameters.
