Hi Tushar,

This error is regarding the material function. This material law(/MAT/LAW36) is an isotropic elasto-plastic material using user-defined functions. The first point of yield stress functions (plastic strain vs stress) should have a plastic strain value of zero.

 

Can you share the files(_0000.rad and  _0000.out) to the dropbox?
