[FLASH-USERS] Help for EOS ERROR (Newton-Raphson failed in multitemp)

[李芳]

Dear All，


I'm using FLASH to simulate the HEDP problem. I'm using two materials (Al+CH) in the simulation. 
The job aborted with the prompt "Newton-Raphson failed in multitemp, multitype Eos.F90" as seen below.
I have succeeded in other simulation using two material. I just changed the target shape. 
Can anyone help me to figure out what's the problem? Thanks very much.
