Thank you! Is there any solution for simulating a heat exchanger?
When I want to simulate "Modelica.Fluid.Examples.HeatExchanger.HeatExchangerSimulation " in default parameter, I see the error page. Why? It is an example. Other examples work properly. In messages browser the error type is "scripting" and there is a text of "Failed to open simulation results...". The following is output log:
stdout | warning | | While solving non-linear system an assert was called.
| | | | | 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
LOG_NLS | warning | nonlinear system fails: Nonlinear function (residualFunc1510, size 160) at t=0
| | | | | proper start-values for some of the following iteration variables might help
