I created 2 blocks of soil and embeded Geogrid in the middle. I created interface between bottom soil/geogrid and top soil/geogrid using tangential option and frictionless. But I got the warning saying
Solver problem. Numerical singularity when processing D.O.F. 1 of 1 nodes. The nodes have been identified in node set warnnodesolvprobnumsing_1_1_1_1_1.
the matrix has 1 negative eigenvalue.
It ran for like 1% of strain and it stopped. I also noticed that the geogrid embeded in the middle was sticking out after apply displacement on the top surface. I was wondering if anyone could help me with this matter to make it run correctly? The boundary condition of the whole mesh is that I put hinge on the corner left bottom and roller on the bottom surface. By the way this is for 2d-plainstrain. The geogrid i used it as a truss for the option material.
