transporter extends forks too high

Hello,

My FlexSim model uses a Transporter to unload pallets of items off of different racks. When I reset the model, the Transporter's forks extend why up high so when I run my model again I have to wait a very long time for the forks to come back down to the floor. I am not sure what could be causing this.

Upon attempting to upload my model, I realized the file size is quite large (37.7MB). I am not using a model background and the overall amount of fixed resources is not significant either. At time0 I create about 800 flow items and then stop creating any more. I am assuming the large file size is causing the visual issues.

If anyone has any ideas as to what could be causing the file size to be so large, please let me know.

My guess is you have inserted 3D media files for objects or items. Even if you don’t use them they are still loaded and available in your model tree.

For this you could also then try saving the model without embedding the media (via Model Settings)

Can you load it into 20.2? If so, then you can have a look at the memory profiler to see what is taking up the space.

@Robert F2, as for the model size question, there is a chance you may have a bunch of historical model run stats information saved in the model file. @Jordan Johnson is there a way to look for that and delete it, if that is the model size issue?

@Ben Wilson @Robert F2 If you have run an experiment, then the results are saved in the model. You can delete most of those results by starting an experiment, and then stopping it before any replications finish.

However, it seems unlikely that the file size is causing any visual issues. Once the model is opened, FlexSim doesn't look at the model file at all, until you either save or load. So I'm guessing that there is some other effect causing the issue with your forklift.

I did have 3D media files in my model. I changed my flow items to not use those media files and I saved the model without embedding the media files and this reduced the file size all the way down to 135kB. However, I am still having the same issue when I restart the model where it freezes and the transporter extends high into the error. Here is the smaller size model.Cell3(Version20.1.2).fsm

This looks like a bug or corruption - loading the model in 21.0 crashes FlexSim. We'll investigate.

I deleted the transporter and the racks in my model and replaced them with new ones. I also deleted the 3D media I had uploaded and this all helped with the issues I was experiencing. My model is running fine now, thank you all.
