For 3D SSI problem in Opensees giving eqdof or rigidlink b/n structure base & proximity stdbrick element node didnt work

I defined my structure with a model builder of -ndm 3 -ndf 6 and my soil as -ndm 3 -ndf 3 with a stdbrick element. I connected the base of the structure with the brick elements with eqdof in dof1 and dof2. my analysis failed :shock: even for gravity load. what kind of constraints did you use to connect the base of the structure to the soil. I aslo tried to use rigid link, but it gave me an error because we cannot connect two nodes which have different dof. Michael midezutd@gmail.com
