Build Status Codecov Coveralls

VisClaw.jl is a Julia package of the Clawpack visualization tools (see http://www.clawpack.org).
This allows to draw figures and animations using the Julia language.

Requirements

  • Julia v1.3.0 or later
  • GMT (Generic Mapping Tools)

Installation

  • If you want to plot using GMT.jl, install the GMT in advance. Note that GMT.jl does NOT install the GMT program.

  • You can install the latest VisClaw.jl using the built-in package manager (accessed by pressing ] in the Julia REPL) to add the package.

pkg> add VisClaw

Usage

  • In preparation, run some of the Clawpack simulations
    (e.g. chile2010 $CLAW/geoclaw/examples/tsunami/chile2010 and
    ike $CLAW/geoclaw/examples/storm-surge/ike).

  • This package uses either GMT.jl or Plots.jl to plot results of the numerical simulation. Plots.jl is more suitable for a quick check. The following codes generate a spatial distribution of the sea surface height using Plots:

julia> using VisClaw
julia> simdir = joinpath(CLAW, "geoclaw/examples/tsunami/chile2010/_output")
julia> plt = plotscheck(simdir; color=:balance, clims=(-0.5,0.5))
>> Press ENTER with a blank to finish
>> Input a file sequence number you want to plot:
checkpoint time (1 to 19) =

Topography data also can be easily plotted:

julia> topo = loadtopo(simdir)
julia> plt = plotstopo(topo)

See Examples_using_Plots.ipynb and Examples_using_GMT.ipynb for more information.
