Saving Input/Output Values and Parameters In Simulation File

Mack 2 weeks ago in IQANsimulate updated by Gustav Widén (System support) 5 days ago 3

Ive saved a simulation file with specific parameters and input/output values but, they dont seem to reliably save. The process here was to run a simulation from design6, setup the parameters in simulate6, then stop the simulation and save. If I run the simulation again, using the file (usually from the last used simulation), sometimes it maintains the parameters but, many times it reverts or changes on a whim. Am I missing something here or is this a bug?

The use case here is that, as our programs grow more complex there is frequently significant setup to get the program to an operating state. IE enabling estop circuits, eliminating alarms, setting inputs to reasonable operating ranges. Being able to save the simulate file with these parameters would save that setup time each time and make it easier for other users less familiar with the program (IE service or techpubs) to simulate what our end users are seeing.

Is it one or multiple .isax files you use?

Is the .idax/.idsx project file the same file you work on? One situation that could be tricky for settings is if the same Project ID has been forked out on different files that are being worked on in parallel.   


Is it parameters (settings) that reverted or did you also see the sliders on input values change?

single .idax file, I had 2 .isax files saved for different configurations I was switching between but, it wouldn't hold the state even if hadn't switched files in between. It was state parameter channels for sure, 90% certain I had a VIN change as well.

If the reset to application default was limited to one state parameter, I'm thinking it could be related to number of states. 

A state parameter will reset to application default if you load a version of the .idax where the number of states is changed compared to what you have in settings.
