I want to model the moving load acting on a single beam in Abaqus. But I can't do it well. Every time I check the data, I get the error message "Surfaces which include edges cannot be used with * contact pair". What should I do now?
The beam is made of one wire part. The tires are made of discretized rigid shell parts. They are created in 3D space.
Hi 彰悟 花村
In the initial step create General contact (Standard) interaction between the beam and the tires.
Hi 彰悟 花村
I meant edge-to-surface contact formulation (something like in the figure).

Now I can't upgrade my Abaqus/CAE to your version 6.21-6. Can you upload .inp file.
Model your tire as a 3-D cylindrical rigid body rather than circular plate.
I modeled the tire as a 3D cylindrical rigid body. But it didn't work. "795 secondary nodes for surface pair (assembly_cp-2-beam-1, assembly_cp-2-wheel-1) are reverted back to type node-to-surface. This case may happen if type surface-to-surface cannot find some nodes Some of reasons are: the secondary is coarser or larger than the main surface, the secondary is not flat relative to the main surface, or secondary nodes that are beyond the extent of the main surface. These nodes have been included. The warning message "in a node set small sliding_ntos_assembly_cp-2-beam-1_assembly_cp-2-wheel-1." Was displayed.
I have an .inp file attached.
The tire model as a 3D cylindrical rigid body is right. In the initial step, you should create General contact (Standard) interaction between the beam and the tire (not surface-to-surface contact).
Try refining the mesh on the cylindrical contact surface. Begin with static simulation (horizontal displacement and vertical load). Inp file will be required as usual.
Yes, you can position the tire on the left edge of the beam. The main goal is to establish the right contact interaction.
