error in computing log values
4 views (last 30 days)
Hi sir..My simulink model runs Good for certain values of input...but for some values it gives a complex computation error.I have used a algebraic constraint solver.
An error occurred while running the simulation and the simulation was terminated

the "log" error was just a consequence of an algebraic loop of OutletEnthalpy bloc : (its input is dependant of the P output)
so probably log of zero or NaN or negative Tad would trigger the error.
simply added a memory block on the P input signal of the OutletEnthalpy bloc and seems the simulation runs fine now (as far I can tell)
