[Paraview] Common problems with Ensight

[Stéphane Montésino]

Hi Renato,

1)To write your data in an unformatted way,  you should use direct 
access and put the reclength.

      reclength=80*3+4*(1+(imax-imin+1)*(jmax-jmin+1)*(kmax-kmin+1)*ndv)

        open (unit=FileUnit,file=trim(GeoName)//'.geo',&
              form='UNFORMATTED',access="direct",recl=reclength)
        write(unit=FileUnit,rec=1)                          &
     &        binary_form                                   &
     &       ,file_description1                             &
     &       ,file_description2                             &
     &       ,node_id                                       &
     &       ,element_id                                    &
     &       ,( part,rank                                   &
     &         ,description_part                            &
     &         ,block                                        &
     &         ,isize(rank),jsize(rank),ksize(rank)            &
     &         ,(sngl(x1(i)),i=lim(1,1,rank),lim(2,1,rank))    &
     &         ,(sngl(x2(j)),j=lim(1,2,rank),lim(2,2,rank))    &
     &         ,(sngl(x3(k)),k=lim(1,3,rank),lim(2,3,rank))    &
     &         ,rank=1,npart)


        open (unit=FileUnit,file=VarFileName,&
     &        form='UNFORMATTED',access="direct",recl=reclength)
        write(unit=FileUnit,rec=1) VarFileName           &
     &                            ,part,rank,block       &
     &                            ,((((SNGl(var(m,i,j,k))&
     &                            ,i=imin,imax)          &
     &                            ,j=jmin,jmax)          &
     &                            ,k=kmin,kmax)          &
     &                            ,m=1,ndv)

 7)To animate a lot of time step, uncheck the box cache geometry  in the 
Keyframe animation menu.
