Beginners quide, FAQ, examples?

[erosenst]

Hello is it possible to add some runable examples in sources directory? (simple .sh with input file?)

I'm currently stuck point where tests gone 100% ok. But how inport/define my endf library to njoy21? Simple commandline example?

I just try simple njoy21 -i input.txt but got:
[error] Encountered unexpected argument
[info] Error while parsing line 8

’PENDF tape for ENDFB-6.8 92235(0)’

input.txt

broadr

So I just try dithering resolution.. Is there any hidden commandline switches or enviroment variables to define where to look input file?
Or simple explanation how to use that program..

This is possibly explained somewhere in manual but not yet find it.. 
Thank you.

Hello, You can find several examples of working input files in the tests directory, and you are invoking NJOY correctly. The particular error you are getting is because input lines with strings must be terminated with a “/”, which you are missing from the first such line under reconr. This website is an old resource, but all the information should still be pertinent despite references to older versions of NJOY. I find it’s often easier than the manual for new users to understand: https://t2.lanl.gov/nis/njoy/

Thank you for reply. I found by strace that it looks input file in same directory and ln -s library file to working dir.'tape20'
Then it run test run.. (removed comments, they seem be unrealible feature)
Your link helps lot.. Examples dir don't helped for my question how link input files but figured it out..

Then try some more complicated and stuck to thermr:

[info] Mat Number: 9228
[warning] Material specific default value not found in table
default value of 25 eV used.

[error] Encountered invalid value for mtref
[info] Error while parsing line 23

0 9228 8 1 1 0 1 221 2

[info] 
mt values are labels for endf sections, where the sections are usually
used to hold different reactions.

The mtref argument is the mt for the desired inelastic option. These
mt values must be between 221 and 250, inclusively.

[info] Trouble while validating THERMR Card 2
[info] Trouble while validating THERMR input
[info] Error while running NJOY21

I used input:
thermr
 0 25 42
0 9228 8 1 1 0 1 221 2
600
0.001 1.0

So it says last element 9th=2 is wrong MT number, range but for documentation it says 8th should be MT and 9th is print option.
Is input syntax changed in njoy21 or what is wrong?

That was just case. njoy21 have ten variables in thermr card 2:

Hi.

NJOY2012 actually modified the NJOY input for card 2 in THERMR - which is causing your issue. It added the iform argument between icoh and natom:

   !  card 2
   !     matde      material desired on endf tape
   !     matdp      material desired on pendf tape
   !     nbin       number of equi-probable angles
   !     ntemp      number of temperatures (default = 1)
   !     iinc       inelastic options
   !                   0     none
   !                   1     compute as free gas
   !                   2     read s(a,b) and compute matrix
   !     icoh       elastic options
   !                   0     none
   !                   1     compute using ENDF6 format data
   !                   --------or for earlier formats
   !                   1     graphite
   !                   2     beryllium
   !                   3     beryllium oxide
   !                  11     polyethylene
   !                  12     h(zrh)
   !                  13     zr(zrh)
   !     iform      output format for inelastic distributions
   !                  0      E-E'-mu ordering (MF6 special)
   !                  1      E-mu-E' ordering (MF6/Law7)
   !     natom      number of principal atoms
   !     mtref      mt for inelastic reaction (221-250 only)
   !     iprint     print option (0=minimum, 1=maximum,
   !                2=max. normal + intermediate results)
   !                (default=0)

This is what is currently in the NJOY2016 manual and in the NJOY2016 source code.
