heatexchangesimulation
Hi,I tried to simulate the HeatExchangerSimulation and got the following error message: (Simulation process failed. Exited with code 0xffffffffffffffff.While solving non-linear system an assertion failed during initialization.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_VWhile solving non-linear system an assertion failed during initialization.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_Vnonlinear system 3431 fails: at t=0proper start-values for some of the following iteration variables might helpSolving non-linear system 3431 failed at time=0.For more information please use -lv LOG_NLS.Failed to solve the initialization problem with global homotopy with equidistant step size.Unable to solve initialization problem.simulation terminated by an assertion at initialization)I am using the nightly version (OpenModelica-v1.20.0-dev-336-g8a791ee46b-64bit) installed on Windows 11Thank you

Separation of real and imag part of Complex number
Hi,I am working on problems which involves complex numbers. Specifically, I solving set of equations and few parameters of results are complex numbers. Now I wanted to separate Real and Imag part of it for further usage but not able to separate it. It is similar as Re and Im functions in MATLAB. Please help me out with it.Thanks
