Recently I wanted to apply HGO model which is a common biomechanical material to human's menisci and unfortunately, I didn't find it in Radioss. Therefore, I decided to realize through user subroutine. However, I couldn't find the coordinate values of each node in the interface code of user material laws 29 as:
SUBROUTINE SIGEPS29 (
1 NEL ,NUPARAM,NUVAR ,NFUNC ,IFUNC ,NPF ,
2 TF ,TIME ,TIMESTEP,UPARAM ,RHO0 ,RHO ,
3 VOLUME ,EINT ,
4 EPSPXX ,EPSPYY ,EPSPZZ ,EPSPXY ,EPSPYZ ,EPSPZX ,
5 DEPSXX ,DEPSYY ,DEPSZZ ,DEPSXY ,DEPSYZ ,DEPSZX ,
6 EPSXX ,EPSYY ,EPSZZ ,EPSXY ,EPSYZ ,EPSZX ,
7 SIGOXX ,SIGOYY ,SIGOZZ ,SIGOXY ,SIGOYZ ,SIGOZX ,
8 SIGNXX ,SIGNYY ,SIGNZZ ,SIGNXY ,SIGNYZ ,SIGNZX ,
9 SIGVXX ,SIGVYY ,SIGVZZ ,SIGVXY ,SIGVYZ ,SIGVZX ,
A SOUNDSP,VISCMAX,UVAR ,OFF )
Actually, the coordinate values of indispensable for defining the anisotropic behavior of HGO model. Could anyone help me to solve it? How to introduce the coordinate values of each node when editing user materials.
