avoid events for efficiency reasons. After importing OMPython and loading the files I use the following command to run the simulation: result = OMPython.execute ("simulate (myGain, numberOfIntervals=2, outputFormat=\"mat\")") The simulation now runs and the results are written to a file. Hi. Modules have facilities for detailed namespace management: each defines a set of names it export s, and can import names from other modules with using and import (we explain these below). However, smooth does not guarantee that no events will be generated, and thus it can be necessary to use noEvent inside smooth. list. Modules can be precompiled for faster loading, and contain code for runtime initialization. test.mo ModelicaReference.Operators.'fill ()' Information Return a Real, Integer, Boolean or String array with all elements equal Syntax fill (s, n1, n2, n3, .) The Sets the default OpenCL device to be used. Many thanks in advance. Counts the number of Initial Equation sections in a class. command: simulate(A); returns true if the definition is a short class definition. How can I change the simulation options like the starting time and ending time (basically time step) without openning OMEdIt. load file (*.mo) and merge it with the loaded AST. The copies the source file to the destination file. It retains the visibility of the class by adding for debugging) without worrying about all the library dependencies.
