Hi,
i run my job and got this ERROR:

For contact pair (assembly_surf-7-assembly_surf-1), adjustment was specified but no node was indeed adjusted more than adjustment distance = 2.22000e-16.

can anybody tell me what is this error and how can i solve it

thanks

Is it an error or just a message stating what nodes of the contact pair have been adjusted and by how much?

Tata but not yet tara
