Records 5 (startup time)
NTTS, IYR, IMO, IDA, IHR, IMN, ISC
Records 6 (geometry and initial condition)
NP, NE, ((CORD(i,J),J=1,2),i=1,NP),
((NOP(i,J),J=1,8),i=1,NE),
(AT(i),i=1,NE),
(ELEV(i),i=1,NP),
(CONC(i),i=1,NP)
where
NTTS
Maximum number of SED2D time steps (see TZ card)
start time
Starting year/month/day/hour/min/second
NP
Number of nodes in the mesh
NE
Number of elements in the mesh
CORD
Array of (x,y) coordinates for each node point (m)
NOP
Element connection table for each element
Element surface area (m2)
AT
ELEV
Initial Bed elevation (m)
Initial concentration (kg/m3)
CONC
Records 7 (solution arrays for current time step)
TETHR, (CONC(i),i=1,NP), (DELBED(i),i=1,NP),
(IMAT(i),i=1,NE), (ELDELBED(i),i=1,NE), (BSHEAR(i),i=1,NP),
(DEP(i),i=1,NP), (NDRY(i),i=1,NP)
where
TETHR
Simulation time, in elapsed decimal hours
Sediment concentration at current time, kg/m3
CONC
DELBED
Bed change by node (m)
IMAT
Element material type
ELDELBED
Bed change by element (m)
BSHEAR
Bed shear stress (Pa)
DEP
Water depth
NDRY
Array containing wet/dry status for each node
(1 = wet, 2 = dry, -1 = About to become re-wet)
Records 7 (through the Last record)
Continue reading simulation in a loop until an end-of-file is reached.
