Error encountered while generating ENDF/B-VIII.1 thermal scattering Data with develop branch

[luohao0925]

I encountered an error while attempting to create thermalization data for ENDF/B-VIII.1 using the latest develop branch. Different nuclides are triggering distinct error messages during the process. I have pasted some examples below, and if there are additional nuclides with similar issues, your contributions to this discussion are welcome.

NJOY Version: develop branch (njoy 2016.77 xxSep24)
ENDF Version: ENDF/B-VIII.1

Error Messages:

• NinUN(NinUNxP, NinUNHEU, etc.) (NinUN-input.txt)

• Uxxx(U, UxxP, UHEU, UinUN, UinUO2, etc.)(U-input.txt)

• YinYH2(YinYH2-input.txt)

• HinLiH(HinLiH-input.txt)

• ZrinZrH2(ZrinZrHx)(ZrinZrH2-input.txt)

I'm seeking insights on why different nuclides are causing distinct errors during the generation process. Any guidance on resolving these specific issues would be greatly appreciated.

Be careful about the "ielas" value in your input ... fourth item on acer card 9. Legacy tsl files have used 0 or 1 for coherent elastic or incoherent elastic data but beginning with ENDF/B-VIII.1 some tsls use a "mixed elastic" format and "ielas" needs to be 2 for NJOY to know about this. And since this is a new format you'll need to use MCNP6.3 to properly interpret the resulting ACE file. Skip Kahler

Thank you for your response! Your input indeed addressed my inquiries about the "ielas" input since the new "mixed" elastic format. I will try with "ielas" of 2. I truly appreciate your help.
