[FLASH-USERS] Tabulated Eos + RadTrans

[Dr. Markus Nöth]

Dear flash team,

I’m working on a modified version of the ZPinch setup. I’ve been experiencing oscillations in the temperature which vanishes when switching off RadTrans. That’s why I’ve switched on the runtime flag rt_computeDt = .true. in flash.par. This worked well as long as I was using an ideal gas law for electrons and ions. Now I’ve switched to tabulated eos and run into the following error

Error message is [Eos] Unrecognized input mode given to Eos

I’ve traced origin of the error to the Eos call in
source/physics/RadTrans/RadTransMain/MGD/RadTrans_computeDt.

The eos mode in this call is MODE_DENS_TEMP_ELE, which is not recognized by the select statement in line 495 in the file
source/physics/Eos/EosMain/multiTemp/Multitype/Eos

The error can be reproduced by compiling the standard magnetoHD/ZPinch example, after setting rt_computeDt = .true. in flash.par.

Why does this happen? Is there a way to use both tabulated eos and rt_computeDT?

Best,
Markus
