[FLASH-USERS] The sesame status data table is missing the 303 part

[Hansen, Eddie]

Hello,

The sesame table reader in FLASH was written for 3T simulations, so it needs the 303 and 304 tables otherwise the code would not know how to partition the energy to ions and electrons. If a sesame material does not have 303 and 304, then you’ll have to use a different kind of table or EOS for that material.

You could potentially “trick” the code by modifying the sesame table yourself before running. For example, create a 303 table that is equal to the 301 table that you do have, and create a 304 table with very small numbers. I’ve never tried this though, so I don’t know how well it would work. This would be assuming near-zero ionization, and the sesame reader always calculates the average ionization via Thomas Fermi…

Dear Flash developers, hello!
        Flash needs to read parts 303（Ion EOS Plus Cold Curve (305 + 306)） and 304 （Electron EOS）of the sesame state equation table, but there is a problem. For substances like water, part 303 is missing in the sesame table found. How to deal with this situation?
Thanks for your answers!!!
