Is there a way to export the data for AStar Paths used?

I'm trying to combine walking paths in AStar to get a better idea of which areas are more highly utilized. Is there a way to export this data?

Software Version:

FlexSim 16.1.2

Unfortunately all of that data is stored internally to the A* Navigator, so there is no access to it.

Hi @Matt Long

Is it still so that one cannot access the data on the A*Navigator to check which areas are more utilized?

If so then one has to use network nodes to get this data from the model, which renders AStar sort of useless for logistics simulations which would be sad.

Thank you!

@Axel Kohonen

Hi Axel, I assume you know about the heatmap option? It is not the actual data but gives you a visual overview. If you really want to dig deeper, under the node "ExtraData" in the stats node of the A* object you will find information about every grid element in your A* area. It is not simple to get it out but it is there.

Hi @steven.hamoen

Thank you for the input!

Yes, I am familiar with the heat map, but generally we always need numerical data so that we can present it in some other way as well and not just with the heat map. The heat map is not very exact in how many traversals there are between certain points. And after getting the visual data from the heat map it would be nice to get e.g. the amount of traversals in certain areas.

Will see if I can manage to understand the Extra Data node then :)

hey @Axel Kohonen! Were you able to figure out a workaround for this? I have a similar problem I am facing with my model of the task executers travelling between racks and I want to get some numerical data for it. Thanks!

Hi @Aditya S2. It has been a while so not sure if I remember it correctly. I think we did in part, but not entirely sure if we ended up using network nodes instead. My colleague @tomi.kosunen created some code that did get the amount of travellers going through a certain area. He had this code in an object that he could put in a certain place in the model and it showed the amount of travellers there somehow.

But we did not get out all the data, just parts of it.
