Input file: Snodes.i

Code reference: subroutine node_allocations in file moz.grids.lib.f

Function: The input file Snodes.i is a plain text file which defines a number of templates for different types of "nodes" (see Glossary for definition of "node" in the context of Mozart). These definitions are used by Mozart to allocate memory for the "node". Snodes.i consists of a series of template definitions. Each template definition contains the following variables:

Variable(s)	Description
itempr	Template number - a number which identifies this template
idoc	Number of lines of documentation which follow. Mozart will read and discard the next idoc lines. This allows a user to provide some comments in the input file which will be ignored by Mozart.
[idoc lines of documentation]
idoc	Number of lines documentation which follow. (This gives the user another comment section.)
[idoc lines of documentation]
ipmode	Number of processor to execute this template If ipmode > 0, then ipmode = number of the processor which should execute this template (i.e. allocate memory for this type of "node"). If ipmode = 0, then all processors will execute this template. This is known as "peer mode".
idoc	Number of lines of documentation which follow. (This gives the user another comment section.)
[idoc lines of documentation]
node_i mesh_i	node_i = node number for which this template applies mesh_i = mesh number for which this template applies If node_i = 0, the subroutine node_allocation will use the value of node_j which was passed as an argument when node_allocation was called. If mesh_i = 0, the subroutine node_allocation will use the value of mesh_j which was passed as an argument when node_allocation was called..
node_topology_type node_sdim node_nx node_ny node_nz node_nextra node_amidnodes maxlnodes i_linkedmesh node_matrix_type	node_topology_type = 1 for tensor product spatial dimension of node [cf. tdim which is target dimension of node] number of points in the node, in the x dimension number of points in the node, in the y dimension number of points in the node, in the z dimension number of extra points in a node maximum number of midpoints in this node maximum number of nodes that you want to link to this node if i_linkedmesh > 0, allocate meshes linked to node (see node_nmeshes) if node_matrix_type=0, will have named arrays for fields; i.e. field names like node_x, node_y, node_vx, etc. if node_matrix_type = 1, all fields will be in node_sources
idoc	Number of lines of documentation which follow. (This gives the user another comment section.)
[idoc lines of documentation]
ilines ich	number of lines to skip over if this processor is not using this template variable used for debugging - must be present
node_nsources	number of additional arrays to allocate
?? variable name(s) ?? 60 integers which have the value of 0 or 1	If the n'th integer = 1, then the n'th field is allocated for this "node" If the n'th integer = 0, no memory is allocated for the n'th field NOTE: the 51st integer and the 52nd integer are special. If the 51st integer is 1, then each of the additional arrays (node_nsources of them) are allocated separately. If the 52nd integer is 1, then one block of memory is allocated to store all of the node_nsources additional arrays.
mesh_nsources mesh_acells	number of elemental cell fields?? maximum number of cells (elements)
nr8b ni4b4	size of the r8 buffer (array) - this should be at least as large as the maximum number of points in a "node", since it must be able to hold an entire field. size of i4 buffer
