EFITI

Acknowledgement

  • Of course, EFIT is EFIT, authored by Lang Lao
  • I have only stripped out D3D and put in ITER character as a replacement - coils are correct but limiting surface is not yet accurate
  • Thanks to Dave Greeenwood for figuring out the LF95 & PGF90 switches and lib ordering so pgplot (g77-gcc) build works properly with either the Lahey or Portland compiler.

Status & Purpose

  • I believe the code is working correctly.
  • My purpose is to provide a tool D3D workers are familiar, which will aid us in assessing ITER.
  • Tools are provided so you can take p’ & ff’ from your favorite equilibria and produce the equivalents using the ITER coil set.
  • I hope this will provide part of the basis for our judging the adequacy of the ITERdesign.

Linux 129x129 only

  • location /d3/EFITI
  • subdirectories are bin cvs efund idl ITER pgplot shape & src
  • Call is /d3/EFITI/bin/efiti129d device k-file
  • Restrictions single k-file input (mode 2 in usual EFITD

Graphics

  • Pgplot graphics devices /xs or /cps
    • if /xs menu items 1-page 4-page are inactive and page 4 is not yet filled
    • if /cps, the pgplot.ps is moved to pshotnum.time at end of execution
  • It may be necessary to set environment:
    • PGPLOT_DIR=/d3/EFITI/pgplot
    • PGPLOT_FOREGROUND=black
    • PGPLOT_BACKGROUND=white
    • PGPLOT_FONT=/d3/EFITI/pgplot/grfont.dat
    • PGPLOT_RGB=/d3/EFITI/pgplot/rgb.txt

Old lessons being relearned

  • Fixed boundary solutions to rshotnum.time produce
    • xshotnum.time+1 a free boundary input file
    • mshotnum.time+11 a reconstruction input file.
  • The difference is primarily iconvr= 3 or 2
  • Fixed boundary is working well
  • Free boundary is working well
  • Reconstruction may need practice

Utilities

  • fixbndy.pro (& fixrbndy.pro)
    • FIXBNDY, gfile KFFCUR=? KPPCUR=?
    • Produces nicely formatted Cα,Xα, & Cγ,Xγ arrays to be appended to an input IN1 namelist.
  • shapel create a fixed boundary input file
  • /d3/EFITI/ITER is intended as a work area and has sample input/output files

Try it

  • I would like to collect interesting cases that our based on D3D results in – /d3/EFITI/ITER/cases
  • Please put input files (along with A and G-files) their for well-converged cases.
  • An example of output follows.
  • Recommendations (or work) for improvement are welcome.

Minutia

  • Response tables in efund with extension .itr are native linun (little-endian)
  • dprobe.dat => rprobe.dat
  • Symmetrize and fitdelz are in &in1 and default to symmetrize=F, fitdelz=T
  • Because of the asymmetry of the outer coils, zelip=0.5 is about right, NOT zelip=0. Perhaps (zelip=.5 relip=6.2 aelip=2. eelip=.16). Recall zelip is measured in D3D.
  • In my limited experience you need to work harder to get a good result than for D3D.
