  Hello,
  I have two solid PARTs, I defined both of them in CESE_PART. Hence Section ID and Material ID need not be defined.
  But still I am getting following error.
  Error 10125 (KEY+125)
  Checking PART and SECTION definition input.
  PART ID 1 with
  SECTION ID 0 does not exist.
  This is PART 1 in the order of input.
  Can you please help on this?
  Regards,
  Atish

  The Dual-CESE method is recommended over the legacy CESE method

  Hello,
  Thanks for the information.
  Can we use *CHEMISTRY card with Dual-CESE method?
  My problem requires use of CHEMKIN files by using *CHEMISTRY_MODEL keyword.

  I have high pressure gas at the centre of cube surrounded by air domain. I am trying to solve sudden expansion of gas in air domain. I am able to achieve mechanical equilibrium (pressure and velocities of the fluid are equal) but not the thermal equilibrium (temp are not exchanged). There is patch of temperature which is constant.
