  • Changed the default Arrivals activities to randomize the created person's visuals.
  • Updated activity subflows so travelers synchronize their speeds when traveling together.
  • Moved copying token labels to the created person to after the people settings labels are added so values aren't overwritten.
  • Added state history tables.

  • Added a chain texture to conveyor belt visual options.

Hi,

warehousing is a great library. Is available a manual? The help is empty. Probably a tutorial to explain the basic idea is necessary.

Which are the compatible NVIDIA card for RTX mode? I have a NVIDIA Quadro P3200, but a popup appear when I active the mode. Isn't it enough or I need to active some graphic card configuration?

Probably I found an issue with transporter. It doesn't update correctly the position during travel task to the source.

The new Warehousing objects do not have documentation yet. We are still working on documenting them. More documentation will be available as we release subsequent iterations of the beta.

A Quadro P3200 is built on the Pascal architecture, which should be compatible with RTX Mode. Try updating your graphics driver and make sure you are using 64-bit FlexSim.

Thanks for pointing out the issue with the transporter. We'll look into it.

The transporter's default Flip Threshold was changed from 180 to 179 so that it would back out of a Drive In Rack by default.

We will change it back to 180 so that it works for this situation by default again, and we will add a note to the documentation of the Drive In Rack about how you can adjust the Flip Threshold to 179 for a Transporter to back out.

Thanks again.

The module Warehousing gets a new basic datatype "bool" for the method hasSpace(treenode item). I am missing the data type announcement in the release notes.

Or should the command hint contain "num"?

We didn't add a new "bool" datatype to FlexScript. That's just what the function returns in C++.

When we update the FlexScript API documentation, it should correctly say "int".

Thanks for pointing this out.

I found an error in the case of using the new storage objects like gravityflowrack etc. The example simple model is the captured;

The error is followed.

The error is same with using transporter.

Thanks for pointing this out. We will fix this for the next beta release.

When 3D modeling using Rack and TaskExecuter, the transporter can not move.

The warehousing objects no longer behave as Fixed Resources using traditional port sending logic by default.

When you connect a fixed resource to a rack (or vice versa), it sets a variable called "Use as Fixed Resource" on the rack that tells the object to use the traditional port sending logic:

(The model also isn't working because Use Transport isn't checked on the upstream Exit Transfer.)

This appears to be a bug that the Rack isn't setting that variable automatically when connecting from a Conveyor. You can manually check the box to fix it. Thanks for pointing this out. I'll add a case to the dev list to look into it.

Hi,

Nice addition with all new racks. Some things I found/noticed:

-When I change the visualization of a floor storage rack to "Repeating bay supports" the visualization is a little bit of. The drawn supports are outside the object. This holds for multiple option in the visualization. I don't know if that is a setting that should change in the GUI or if it is a small bug (see picture)

-If you don't drag in a Storage system object you are not able to change the visualization of the rack objects. Not sure if that is intentional or not. I guess I will need to read the manual when it is there.

-The option to collapse event in a wait for event is really nice, it would how ever also be nice if you would be able to remove the first event from a wait for event, now all events can be removed but the first not. Is this something that is forgotten or would this be a new feature?

Thanks for the new Beta.

1. We'll look into the weirdness of trying to use visualizations on the floor storage that weren't designed for floor storage. Thanks for pointing that out.

2. This is by design. The objects use default visualizations if you don't have a Storage System in your model. If you want custom visualizations, you need to add a Storage System.

3. This has always been that way. In 19.2, we just made it so that the UI is collapsible so that large lists of events don't take up so much real estate on the screen that you can't access the entire popup. I'll add a case to the dev list to consider being able to remove the first event from the list.

Thanks for the feedback.

1. We've fixed the weirdness of the visualizations drawing outsize of the floor storage area in the 9-Aug beta.

2. We've changed the Storage System object so that it gets asserted when you create a Rack instead of needing to explicitly add it. This way, you'll always be able to see the visualization options.

Thanks again.
