STEP-1
Example 1 for DEALII

STEP-1 is the first example from the official DEAL.II example directory. It is included here primarily to illustrate the steps necessary to run a program that uses DEAL.II.

This script is set up for a very specific situation involving the FSU RCC cluster. In this case, programs are run using the SLURM batch queueing system.

DEAL.II has an examples directory, and the first example is in the step-1 subdirectory. I would recommend making your own working directory, and copying from the /usr/local/dealii/examples/step-1 directory the following two files

• CMakeLists.txt
• step-1.cc

Now in that directory, you need to create, one time, the necessary makefile, by issuing a command something like:

        cmake -DDEAL_II_DIR=/usr/local/dealii .
      

If all goes well, then you can create the step-1 executable by

        make
      

Files you might find useful:

• CMakeLists.txt, the file needed by cmake on my system.
• step-1.cc, the source code for the example.
• step-1.sh, a SLURM script which contains the commands to create the makefile and run the example.
• step-1_output.txt, the output printed by the program.
• slurm-2881002.out, the output returned by SLURM.
• grid-1.eps, the PostScript image of mesh 1.
• grid-1.png, the PNG image of mesh 1.
• grid-2.eps, the PostScript image of mesh 2.
• grid-2.png, the PNG image of mesh 2.

You can go up one level to the DEALII directory.
