GMS:SEEP2D Files

This page is a start at documenting SEEP2D file formats. It is not complete.

List of Files

SEEP2D Files

Name	GMS Extension	Format	Description
Data	.s2d	ASCII	Main input file read by SEEP2D
Super file	.sps	ASCII	GMS "super" file. Read and written by GMS. Lists all the SEEP2D files related to a simulation. Also contains other data needed by GMS but not contained in the main SEEP2D data file.
Data set solution file	.ssl	Binary	A file containing the GMS data sets which are the SEEP2D solution. Read by GMS. Created by SEEP2D when it solves a model.
Out file	.out	ASCII	Created by SEEP2D as it solves the model. Includes the model description as it read it from the main data file, and the solution.

SEEP2D Data File Format

Line	Contents
1	hed hed = A heading for the simulation
2	numnp numel nummat nflcd lplx datum flonet unitwt iuntyp numnp = number of nodes numel = number of elements nummat = number of materials nflcd = number of flux bc lines lplx = flow type datum = vertical datum flonet = flow net unitwt = unit weight of water iuntyp = model type. 0, 1 or 2
3	matid k1 k2 angle kro ho vanalpha vann mat = material ID. Any integer number, not necessarily in order. k1 = k2 = angle = kro = ho = vanalpha = vann = Repeat for all materials
4	node ? nbc x y fx node = node number ? = ? nbc = bc type x = x location of node y = y location of node fx = ? Repeat for all nodes
5	element node1 node2 ... matnum element = element number node1 = node number 1 node2 = node number 2 matnum = The number of the material associated with this element as defined on line 3. This is not the matid, which can be any number, but the ordered index of the materials listed on line 3. For example, if line 3 lists 2 materials with IDs of 7 and 5 in that order, then matnum will be 1 for material 7 and 2 for material 5. Repeat for all elements
6	node1 node2 fluxrate node1 = number of node on one side of element edge node2 = number of node on other side of element edge fluxrate = rate of flux for the edge described by node1 and node2 Repeat for all flux BCs
