Hello, is there a way to define a custom property that uses properties from Particles and Contacts, or more generally, properties from multiple modules? I'm looking to calculate a stress value per particle that uses Particle properties (particle size, coordinates, ID) and Contacts properties (contact coordinates, normal force components, particle ID from). I see that custom properties only have access to the properties in that module. I've looked at User Processes for Particle to Contact and Contact to Particle, but I don't think that solves the problem.

Otherwise, am I stuck to using the PrePost script to analyze it in post-processing?

Dear Seijieng.

It is not possible to define a custom property in Rocky DEM that directly combines data from both Particle and Contact modules. Custom properties are limited to their own module’s properties. For combined analysis, post-processing with PrePost scripts is required.
