How to remove warning when using uniaxialMaterial BoucWen?

Post by gooddaytogo » Thu Apr 21, 2022 2:04 pm

Hello, everyone,

I am using the uniaxialMaterial BoucWen to simulate the material degradation, but when I was doing the static analysis, I saw the following warning in the calculation, anyone knows how to solve it? Thanks.

WARNING: BoucWenMaterial::setTrialStrain() -- did not find the root z_{i+1}, after 20 iterations and norm: 8.71013e-08
