Simulate thermopower pump error code -1

[Félicia]

I want to developp a simulation of power plant. At the beginning, I simulate each components of the power plant power (condenser, turbine, pump...).

For the pump, I use source pressure and masse flow and sink pressure.

I initalized pressure and enthalpy.

And I have a error message :

stdout | warning | While solving non-linear system an assertion failed.

| | | | | The non-linear solver tries to solve the problem that could take some time.

| | | | | It could help to provide better start-values for the iteration variables.

| | | | | For more information simulate with -lv LOG_NLS

| | | | | | [2] Real pump1.rho(start=1000, nominal=1)

| | | | | | [3] Real pump1.s(start=1, nominal=1)

Use -lv=LOG_INIT -w for more information.

Process crashed

Simulation process exited with code -1

I don't understand why it doesn't work.

Could you help me for this error?

Where can I have information about error compilation and about model of thermopower library?

Thank you

Best regards
