INTERFACE_SUMMARY Summary Forces on All Contact Surfaces
INTERFACE_SUMMARY Summary forces on all contact surfaces
This lists the global [x,y,z,magnitude] force vectors for all contact surfaces. The values are computed from the individual nodal forces in the .CTF file, and are presented separately for A and B sides of each surface.
| Note 1: | Normal contact surfaces with both A and B sides will have equal and opposite forces on each side. For example surface #1 here. |
| Note 2: | The contact force file only contains forces for nodes on segments. Where discrete nodes form one side of a surface then no forces are written for that side. For example surface #4 above is "Discrete nodes (A side) impacting surface (B side)", and forces only appear for the B side. |
| Note 3: | Single-surface contacts only have an A side, and the net force on such a contact surface is zero. However plots will show a distribution of force on the individual segments of the contact. |
| Note 4: | Contact surface types using a one-way treatment (eg types 10 and 21) write forces for the B side only. Surface #3 above is such a surface. |
| Note 5: |
Contacts using a constraint rather than a penalty formulation do not generate forces. (However contacts using "soft constraint" still generate forces.) |
