Parameter definition

Variable
Description
entype
Entity type
options: M, P, PS, DP, RB
enid
Entity ID
fid${}_{xx}$
ID of FUNCTION defining $\sigma_{xx}$ as function of $(x,y,z)$
fid${}_{yy}$
ID of FUNCTION defining $\sigma_{yy}$ as function of $(x,y,z)$
fid${}_{zz}$
ID of FUNCTION defining $\sigma_{zz}$ as function of $(x,y,z)$
fid${}_{xy}$
ID of FUNCTION defining $\sigma_{xy}$ as function of $(x,y,z)$
fid${}_{yz}$
ID of FUNCTION defining $\sigma_{yz}$ as function of $(x,y,z)$

multi
Treatment of multiple commands
options:
0 $\rightarrow$ stresses from previous commands are overwritten
1 $\rightarrow$ stresses from multiple commands are superposed
2 $\rightarrow$ stress component with largest absolute value is kept

Description

Definition of initial stresses. For rebars (entype=RB) fid${}_{xx}$ is used to define the axial stress.
