How to use the aniso code

Before starting using the aniso code, the user decides if he/she wants to use the tables or not and if he/she wants to use the Voigt or the Reuss averages for mu and nu.

To use the tables, turn on DEFS += D_TABLES in the makefile. To create the table files, set QSBMETHOD = 1 in tabulate.c. To read the table, make sure they are located in the inputs directory.

To set the mu and nu variables, set #define VOIGT and #define REUSS variables in ANI_Util.c

Flow chart of the aniso code

ANI_Main

defines the directory where files Qtable.dat, Stable.dat and Rtable.dat will be created or read. define the aniso0 structure calls ANI_Init in ANI_Utils.

ANI_Init

initialize the aniso0 structure. . define C, eps

. define mu and nu. User can choose between the Voigt or the Reuss averages.

. calls the routine that defines Q, S, B. Uses file QSBMatrices.c

. user can choose to read in tables (QSBMETHOD = 1) in tabulate.c or not.

Param.c and Param.h

defines variables specific to aniso code: C12, C44, Cpr. Also defines the tables files.

NodeForce.c

When the ANISOTROPIC flag is on, use anisotropic SelfForce. The SeflForce routine calls QSBMatrices.c routines to get the QSB matrices.

LocalSegForces.c When the ANISOTROPIC flag is on, use anisotropic SegSegForces. This routine calls ComputeANIForces located in Stress.c.

Stress.c

ComputeANIForces.c calls the ANI_WillisSteeds function also located in Stress.c. ANI_WillisSteeds decide whether to use the regular definition or the collinear one.

That's it!
