Dear all
I'm trying to simulate the cohesive contact between a deformable sphere and a rigid plane using cohesive surfaces
The sphere is in a first step compressed against the surface. Thereafter, the sphere should be sheared along the surface until fracture of the cohesive surface
To avoid damage of the cohesive surface and to use the same setup for different parameters in the cohesive zone I decided to do the compression in a first analysis
and the shearing using the restart ability.
The problem is that when I am running the restart file I get the following error:
"Node set assembly_instance2_instance2-refpt_ has not been defined
Unable to locate node set assembly_instance2_instance2-refpt_. The node set must have been previously defined.
*rigid body reference node is 0."
Probably occurring due to the warning:
Instance "INSTANCE2" cannot be imported. No section assignments have been found in the output database file.
I am importing the model from the input-file created in the compression analysis
How to solve this issue? The same methodology but with contact between two deformable spheres worked perfectly
I attach the both python files that creates the model and compresses the sphere, "sphere-plane.py" and the script used for restart, "restart-spheres.py" together with the inp file generated by the first script, "particles.inp"
Thanks in advance
