Fort.14: Grid and Boundary Information File

The fort.14 file contains the finite element grid, the bathymetric data, and the boundary information used by ADCIRC. This file is required to run the ADCIRC model.

File Structure

This file contains 4 sections: nodal data, element data, open boundary data, and flow boundary data. The basic file structure is shown below. Each line of input data is represented by a line containing the input variable name(s). Loops indicate multiple lines of input. Conditional input is indicated by a clause following the variable name(s).

AGRID
NE, NP
for k=1 to NP
   JN(k), X(k), Y(k), DP(k)
end k loop
for k=1 to NE
   JE(k), NHY(k), NM(k,1), NM(k,2), NM(k,3)
end k loop
NOPE
NETA
for k=1 to NOPE
   NVDLL(k), IBTYPEE(k)
   for j=1 to NVDLL(k)
      NBDV(k,j)
   end j loop
end k loop
NBOU
NVEL
for k=1 to NBOU
   NVELL(k), IBTYPE(k)
   for j=1 to NVELL(k)
      NBVV(k,j)      if IBTYPE(k) = 0, 1, 2, 10, 11, 12, 20, 21, 22, 30
      NBVV(k,j), BARLANHT(k,j), BARLANCFSP(k,j)      if IBTYPE(k) = 3, 13, 23
      NBVV(k,j), IBCONN(k,j), BARINHT(k,j), BARINCFSB(k,j), BARINCFSP(k,j)      if IBTYPE(k) = 4, 24, 64
      NBVV(k,j), IBCONN(k,j), BARINHT(k,j), BARINCFSB(k,j), BARINCFSP(k,j), PIPEHT(k,j), PIPECOEF(k,j), PIPEDIAM(k,j)      if IBTYPE(k) = 5, 25
   end j loop
end k loop

Open Boundary Data

See open boundaries for details of the open boundary data.

Normal Flux Boundary Types

See flux specified boundaries for details of the normal flux boundary types. See also IBTYPE for full details of each boundary type.

Example

The following is a simple example of a fort.14 file for a small domain with 3 elements and 4 nodes with an open boundary and no flow boundaries:
