I have a very large excel file, and FlexSim crashes when trying to import it all at once, even after doing data cleaning and separating it into 12 different files. So, I would like to import it into FlexSim as needed by the model, for example, every 1 hour of running the model, 10000 rows are imported. I started using FlexSim recently, and I don't know if the best way to solve this problem is with FlexScript in the 'Custom Code' option, or if I should integrate my FlexSim with FlexSimPy. Could someone help me?
