GUI cannot specify thermal conductivity

version:19.2.1
GUI
description: solid thermal conductivity is always blank even if I enter a number (it will constantly go back to blank).
Seems it is only the problem of GUI, because the .mfx file successfully changed after saving. And the comman line shows “k_s0(1)=xxx”

Thanks for the bug report. I found this reviewing old forum posts. This has been fixed as of MFiX version 20. Closing the topic. Please continue to report any bugs you find in MFiX! Thanks.
