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:
