  Hello Ansys Learning Support Team,
  I used the tutorial provided here https://innovationspace.ansys.com/knowledge/forums/topic/how-to-access-the-value-of-an-expression-at-the-previous-time-step-without-using-userfortran/ to get the value of an expression at the previous timestep without using UserFortan, this was by using a monitor point and arithmetic sum method above. (I didn't used the derivative method as I need to run the simulation in steady as well). I have managed to use this to get the value of p(t-1) and q(t-1) for previous timestep for 3 outlets. Thank you.
  As my simulation is unstable at initialisation due to the 2 small outlets, I've had to run a steady simulation to initialise this see below table for variables obtained. The steady simulation also finished with the p(t) and q(t) current timestep which can be used. Then I also defined the p(t-1) and q(t-1) terms to be inialised when starting the transient simulation as it initialises at 0 by the solver by default otherwise (due to automatic with value) causing those 2 small outlets to diverge.
  | Courant Number | 2.27E-05 | 5.65E+02 |

  | pout1prev | 8.31E+03 | 8.31E+03 |
  | pout2prev | 8.31E+03 | 8.31E+03 |
  | qout0prev | -9.59E-07 | -9.59E-07 |
  | qout1prev | 1.13E-06 | 1.13E-06 |
  | qout2prev | 1.39E-06 | 1.39E-06 |
  | Velocity | 5.53E-10 | 7.13E-01 |
  | Dynamic Viscosity | 4.00E-03 | 4.00E-03 |
  However when I now set up the transient model, having tried to create the AVs and linked to default domain expressions, I am now getting this error. I would be very grateful for your assistance and can send the CFX file to an Ansys Employee. This is the error The parameter 'Expression Value' is defined to be Single Valued but it depends on the field variable: qout0prev Error processing expression: Expression Value = pout0

  Hi,
  It seems that the expression pout0 has inadvertently connected to qout0prev. I kindly request you to carefully review all the expressions, as this may be a minor issue that can likely be resolved with a thorough check.
