Rigid body impact with steel plate, Error with too many atempts for this increment
I am getting this warning message many times " system matrix has 1 negative eigenvalues", strain increment too large, and finally stop with the error "Too many attempts made for this increment.
I modelled a Steel Barge(front part of ship) with shell elements and it is impacted by a rigid body. When the rigid body was given a displacement of 2.5 inches it runs. But when I increase the displacement to more than that it doesnt work. I should get the Force displacement behaviour of barge by impacting this rigid pier in to it at least 20-40inch.
