  Hello all,
  
  I just migrated to Fluent 2020 R1. I want to use pressure based and p-v-coupling 24 model. However, when setting this, I am not able to control the courant number and under-relaxation factors.
  
  I would really appreciate your help!
  
  Thanks a lot beforehand.
  
  Best regards,

  Hello Fran,
  
  The default setting for the Coupled scheme uses Pseudo-Transient under-relaxation. You will be able to set the courant number if you turn this feature off.
  
  Thanks,
