CLAWPACK Sample Code

Elasticity equations in a region consisting of two materials with a corner.

mx=400, my=400 was used for the plots in the book.

The elastic parameters are defined in and the inclusion geometry is specified by fdisc.f Elastic parameters in each cell are set in setaux.f

The wave is generated by specifying a right-going P-wave in qinit.f

Example [book/chap22/corner] to accompany the book
   Finite Volume Methods for Hyperbolic Problems by R. J. LeVeque.

Converted to Clawpack 4.4 form in 2010.

Plots of results

After running this code and creating plots via "make .plots", you should be able to view the plots in _plots/_PlotIndex.html .

Fortran files

Makefile [.html]
Determines which version of fortran files are used when compiling the code with make and specifies where output and plots should be directed. Type "make .help" at the Unix prompt for options.

driver.f [.html]
The driver routine allocates storage and then calls the main Clawpack routine.

setprob.f [.html]
A routine by this name is called by the library routine clawpack/2d/lib/claw2ez.f [.html] and is generally used to set any values needed for the specific problem being solved.

rpn2.f [.html]
Normal Riemann solver (normal to cell interface).

rpt2.f [.html]
Transverse Riemann solver.

qinit.f [.html]
This subroutine sets the initial data at time $t=0$.

Python files [.html]
This file contains a function that specifies what run-time parameters will be used.

Some parameters that you might want to modify are described in the documentation . [.html]
This file contains a function that specifies what plots will be done and sets various plotting parameters.

Data files

Warning: These files are generally changed when setting up a run, usually in [.html]. [.html]
This file contains a number of parameter values that are used by CLAWPACK. The values in this file are read by the library routine clawpack/2d/lib/claw2ez.f [.html]. [.html]
This file may contain various parameters used in setting the initial conditions or otherwise setting up the problem.

Library routines

In addition to the Fortran routines in this library, several library routines from $CLAW/clawpack/2d/lib are used. See the Makefile [.html] to determine which ones are used.
