Hello
I am trying to model a thermal fluid system where a furnace provides heat to pipe TL in simscape. at the moment, the mass flow rate of the fuel is 0, but i get the following errors:
At time 20.000000, one or more assertions are triggered. Temperature at port A must be less than or equal to Maximum valid temperature. The assertion comes from: Block path: pumpandpipe07082024/Pipe (TL)Assert location: o (location information is protected) o (location information is protected)
Ungroup 25 similar
Component:Simulink | Category:Model warning
An error occurred while running the simulation and the simulation was terminated
Caused by:
  • Derivative of state 'pumpandpipe07082024.Pipe_TL.segment.p_I' in block 'pumpandpipe07082024/Pipe (TL)' at time 50.0 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)
