2694	Simulate thermopower pump error code -1	Félicia	Adeel Asghar	"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.

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

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
