Topic: Dump on the surface

Hi, during the analysis through ATENA, sometimes, there will have a sharp dump on the surface. Is there any possible method to solve it?

Kind regard,
Jia

Re: Dump on the surface

Dear Jia, I am not sure what you mean - maybe a bump? Can you send some screenshots, your model, etc. (Troubleshooting, 2.1.1)?

Just guessing: you may be interested in Troubleshooting, 2.1.19 Problems reaching convergence and understanding ATENA convergence parameters or/and 2.4.6 Floating point problems - Division by zero, Loss of >7 digits on the matrix diagonal, CCFEModelExc: CCPardiso solver error: zero pivot,  Warning: Sign of diagonal changed when reducing equation, Floating point exception: Multiple floating points traps, Zero or negative jacobian,  InvertA: zero determinant, CCMaterials Extended AExc: CC5ParamYield F: project_stress_on_f_division by zero, and similar.
