Objectives of Project Frontal model running on SGIs instead of JEDI. View model output. Determine initial conditions of over 100 previous runs. Learn some new tools.

Viewing Model Output t u v w - Needed to take model output 1 1 1 1 1 1 1 1 2 2 2 2 . . . . . . . 8262 8262 8262 8262 - Needed to take model output and put in grid that Matlab or Ferret would understand. Outfiles are for a specific time since initial condition If model grid was 51X162 output file looks like this

Wrote a Matlab program to put data in proper format: t u v w 1 1 1 1 2 2 2 2 . . . . . . . 8262 8262 8262 8262 51 102 154 . . 8262 50 . . . . . . . . . . . 3 . . . . . 2 . . . . . 1 52 103 . . 8212

Sample Initial Conditions RUN 103

RUN 106a and Run106b

Useful Tools Discovered GDIFF - allows you to view two files side by side and highlights differences.

Green = Totally new lines Yellow = Difference in lines

Another Useful Tool Case Vision - Application debugger - allows you to step through the program - shows you the flow when there are many subroutines - Array Visualizer - view arrays as spreadsheets http://www.cc.gatech.edu/gvu/people/Phd/Reid.Harmon/cvt/#Debugger Useful website

Did I achieve the objectives? - Model runs on the SGIs, but output is not the same. Skill working on this. - Yes, I can now view model output. - Still working on compiling initial conditions of previous model runs.
