assign pressure initial condition on a flexible porous wall
Dear friends
I am doing Transient analysis.The flow is in the z direction in a flexible porous pipe. model inlet condition : pressure(t), outlet: Mass flow rate I have data as shown below t=0s, p= 130mmHg t=0.1s , P= 135mmHg and so on. No other data I have. I need to set Global initial conditions on fluid domain and porous domain. I set the initial conditions in the fluid domain as shown below : static pressure> Option>Automatic value with value>Relative pressure = 130 mm Hg Is it correct? I set velocity U=0m/s, V=0m/s , W= 0.4m/s (for example) similarly I need to set initial conditions in the porous domain. Kindly help me to set the initial conditions. I set U=0 m/s , V=0m/s , W=0 m/s static pressure> Option>Automatic value with value>Relative pressure = ? Is the pressure is same as 130 mm Hg or 0 ? Kindly help me to proceed my simulations Thank you Regards Govind |
What mass flow do you have at the outlet?

My outlet dia= 2.5mm I am expecting flow 1.96ml/s at the outlet Thank you Regards Govind |
So you have a constant flow rate leaving the domain with a variable pressure being applied? This sounds unusual. Is the fluid compressible or incompressible?
I have no idea what you are modelling so cannot comment on whether it is sensible or not - but so far it sounds strange. |

it is incompressible flow in a artery . it is an average flow in one cardiac cycle. |
In that case this is likely to be a FSI simulation.
Are you having any problems in running this? What is your question? |

My question is 1. I consider arterial wall as porous domain. What is the initial condition in the wall domain? Thank you Regards Govind |
