Structural + EDEM(External)

Description

  1. Structural-EDEM coupling allows coupling the advanced structural analysis capabilities of OptiStruct with bulk and granular material interaction capabilities of EDEM. You can simulate and analyze the interaction of materials such as coal, soils, grains etc. with deformable surfaces. It is currently only supported with Explicit Dynamic Analysis (NLEXPL) subcases.

  2. The particle type, material, interaction physics data should be defined in EDEM. Additionally, the interface surface material information should be defined both in OptiStruct and EDEM and they should be consistent with each other. In OptiStruct, the interface surface material data is used to calculate the deformation behavior of surface, while in EDEM, the interface surface material data (defined under Equipment Material) is used to calculate the contact forces during the interaction between the particles and the surface.
  3. The Coupling Interface surface is defined only in SimLab. The first Equipment Material data defined in EDEM is used as the material data for all coupling surfaces. The coupling surface(s) are exported to EDEM by OptiStruct during the initialization of coupling.
  4. To initiate an Structural-EDEM (External) coupling run, the Coupling Server should be started in the EDEM GUI, and the EDEM model should be loaded into the EDEM Creator GUI. Then please check to make sure that the “Current Time” is set to 0.0 in EDEM Creator GUI. Then use Coupled Solution > Results > update option to start the coupled simulation.
