So i should use petsc-dev ? I will try that.
I there any way i can have access to submesh? Consider a this scenario.
I have a two dimensional mesh in a rectangle with a uniform deltaX and
deltaY gridding. Is there any way i can get submesh at say x = (i-1)*deltaX
where say i = 1 to N. The dofs on the submesh will should be mapped to
dofs on the original mesh. The submesh in this case will be a 1D mesh
along y-axis.
I can create each DM with input celllist and create maps after that but i
am wondering if this can be done via DMgetsubDM kind of call ?
Thanks
Reddy
