Question #692174 on Yade changed: https://answers.launchpad.net/yade/+question/692174 Status: Open => Answered Robert Caulk proposed the following answer: >So based on your response, clumps cannot transfer heat between their members but can be homogeneously heated. At the moment, the thermal behavior of clumps is undefined. However, cohesive materials or cohesive agglomerates do work in ThermalEngine. If you need clumps with ThermalEngine, you need to modify the source code.
