Hi Paul,
Thanks a lot. Your .box file is also running. Mine is not...
I have only modified the dimensions of the mesh according to what I
need. Do you see anything wrong?
rbsissa2d.rea
2 spatial dimension
1 number of fields
#========================================================
# Here is a multibox example
#========================================================

Box left lower
-3 -2 nelx,nely,nelz for Box)

Box left center
-3 -3 nelx,nely,nelz for Box)
