Re: [TRNSYS-users] The smooth results suddenly are changed to "NaN"
Reza,
NaN stands for "not a number" and it is usually the result of a model dividing by zero internally. In order to find where the NaN occurs, it is necessary to run your simulation using the line by line debugger in a fortran compiler. If you don't have a compiler and have checked your *.m code to make certain that it cannot produce a division by zero then it might be helpful to know how this NaN is being reported (is it in the lst/log files? is it reported as a FORTRAN error on screen?) in order to get a better idea of where you might look for the problem.
Kind regards,
David

Dear all TRNYSY users,
Indeed, I am using two Types155 in series, in which the results from first one are used by next one.
*** Problem:
Once I run the simulation for 9000 experimental input data, the simulation runs smoothly for 1370th data but suddenly it produces simulation results as NaN.
I would appreciate if you could help me what the source of problem is. :)
