Modeller crash while updating nodes/links at the roundabouts in Paramics model

Product Feature: Modeller


If nodes at the roundabouts are to be changed from “normal” nodes to “roundabout” nodes or any other Update is to be done, it requires updating each node so that only a maximum number of incoming/outgoing links are attached to a particular node. This leads to the Paramics Modeller crash.


This has been identified as a defect a product.


UPDATED: October 16, 2019
In order to update nodes, follow these steps:
  • Delete the nodes from the nodes file.
  • Make the necessary changes to the network model.
  • Save the network.
if above does not help:
  • Remove the spatial tests 
  • Delete the links.
  • Create roundabouts again.
