Hope the code chunk below, can help identify the issue.<br>
<br>
The following is the sequence of calls:<br>
<br>
DM :: dm<br>
Vec :: localX<br>
InsertMode :: mode<br>
PetscErrorCode :: ierr<br>
!<br>
PetscSection :: section ! defualt section<br>
PetscScalar,allocatable :: values(:) ! size numDofPerPoint<br>
integer :: vertexId<br>
integer :: vertexIdStart, vertexIdEnd<br>
integer :: vertextdim<br>
integer :: numConstrainedDOF<br>
integer :: rgnId,bcId,offset<br>
integer :: IdStart,IdEnd<br>
integer :: fc<br>
vertextdim = 0<br>
call DMPlexGetDepthStratum(dm,vertextdim,vertexIdStart,vertexIdEnd, ierr)<br>
call DMGetDefaultSection(dm, section, ierr)<br>
call PetscSectionView(section,PETSC_VIEWER_STDOUT_SELF,ierr)<br>
allocate(values(this%dofMap%numFieldComp))<br>
print*, 'size of values is',this%dofMap%numFieldComp<br>
do vertexId=vertexIdStart,vertexIdEnd-1<br>
call PetscSectionGetConstraintDof(section,vertexId,numConstrainedDOF,ierr)<br>
print*,'vertex dof',vertexId,numConstrainedDOF<br>
if(numConstrainedDOF > 0) then<br>
call DMPlexGetLabelValue(dm,'Boundary',vertexId,rgnId, ierr)<br>
values = 0.0_WP<br>
offset = 0<br>
do fc = 1,this%numField<br>
! check if Field at vertextId is contained<br>
IdStart = offset + 1<br>
IdEnd = offset + this%numComp(fc)<br>
!if(fieldIdisconstrained) then<br>
bcId = this%getBCId(fc,rgnId)<br>
values(IdStart:IdEnd) = this%BC(bcId)%getBC()<br>
!end if<br>
offset = offset + this%numComp(fc)<br>
end do<br>
print*,'Setting bc value',values(1),'at vertex',vertexId,rgnId<br>
call VecSetValuesSectionF90(localX, section, vertexId, values,Mode,ierr)<br>
end if<br>
end do<br>
deallocate(values)<br>
<br>
The three print statements above print the following lines.<br>
<br>
size of values is 1<br>
vertex dof 600 1<br>
Setting bc value -35.7688912272406 at vertex 600 1<br>
<br>
So, i am passing the correct size array to VecSetValuesSectionF90.<br>
However, when i run the code through intel debugger, i get the<br>
following:<br>
<br>
size of values is 1<br>
vertex dof 600 1<br>
Setting bc value -35.7688912272406 at vertex 600 1<br>
Program received signal SIGSEGV<br>
VecSetValuesSection (v=0x2bf5620, s=0x2b41a60, point=600,<br>
values=0x447e3d3b071996fc, mode=INSERT_BC_VALUES<br>
) at /home1/00924/Reddy135/LocalApps/petsc/src/vec/vec/utils/vsection.c:185<br>
185 if (doBC) array[i] = values[i]; /* Constrained update */<br>
(idb) print values[0]<br>
$1 = <no value><br>
<br>
<br>
The value i passed from Fortran code is not missing.<br>
<br>
The relevant call trace is:<br>
<br>

<br>
<br>
Am i doing some thing wrong ?<br>
<br>
Thanks<br>
