Inputs

Section titled “Inputs”

Tolosa-lib provides flexible input management through:

  • Command-line arguments
  • Text configuration files (input.txt)
  • YAML configuration files
  • User-defined functions (m_user_data.f90)

Command-Line Interface (CLI)

Section titled “Command-Line Interface (CLI)”

The type(cli) structure allows passing arguments via command line:

Terminal window
./exe -nx 100 -ny 100 -dt 0.1 -t_end 100.0

Input Text File

Section titled “Input Text File”

The input.txt file contains simulation parameters:

# Domain parameters
nx = 100
ny = 100
lx = 1000.0
ly = 1000.0


# Time parameters
dt = 0.1
t_end = 100.0


# Output parameters
output_frequency = 10

YAML Configuration

Section titled “YAML Configuration”

For complex configurations, use YAML files with the type(yaml_file) structure:

domain:
  nx: 100
  ny: 100
  extent:
    lx: 1000.0
    ly: 1000.0


time:
  dt: 0.1
  t_end: 100.0


output:
  frequency: 10
  format: vtk

User-Defined Functions

Section titled “User-Defined Functions”

The m_user_data.f90 file contains user-defined Fortran functions for:

  • Initial conditions
  • Boundary conditions
  • Source terms
  • Custom bathymetry
