NOTE: this package is unofficial and the author is not engaged in the Clawpack Development Team.

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

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 Makie.jl or GMT.jl to plot results of the numerical simulation. Makie.jl is more suitable for a quick check. The following codes generate a spatial distribution of the sea surface height using Makie.jl (CairoMakie.jl):

julia> using VisClaw
julia> simdir = joinpath(CLAW, "geoclaw/examples/tsunami/chile2010/_output")
julia> fig = quickview(simdir; colormap=:balance, colorrange=(-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> fig = makietopo(topo)

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