|

|
|
! Called by all solvers in mesh_init in order to initialize the ip coordinates.
|
||
|
|
! Later on the current ip coordinates are directly prvided by the spectral solver and by Abaqus,
|
||
|
|
! so no need to use this subroutine anymore; Marc however only provides nodal displacements,
|
||
|
|
! so in this case the ip coordinates are always calculated on the basis of this subroutine.

! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
|
||
|
|
! FOR THE MOMENT THIS SUBROUTINE ACTUALLY CALCULATES THE CELL CENTER AND NOT THE IP COORDINATES,
|

|
|
! AS THE IP IS NOT (ALWAYS) LOCATED IN THE CENTER OF THE IP VOLUME.
|
||
|
|
! HAS TO BE CHANGED IN A LATER VERSION.
