Hi,

I am using the Abaqus Standard for a stationary crack modeling. At the beginning of my simulation I am getting some negative eigenvalue warnings, but simulation runs. This makes simulation to go very low time increments. Before I reach to my desired deformation level, my simulation results an error saying that time increment required is less than the minimum specified. I do not want to go lower time increments because it will take forever. Absurd crack front deformation is attached.

What would you suggest ? How can I solve this problem ?

Thank you.
