User Subroutine for Inlet Velocity

Hello everyone.I need a small favour to ask.If someone could guide me and provide me with a very close subroutine that serves the purpose I am trying to do.I have done the part in the GUI but want to use a subroutine in the hope that it will reduce my simulation time from 1.5-2 days to less time.

Reference Velocity,Pressure

Could someone explain please what are these parameters for as they seem to affect my solution running or aborting. My assumption is that they are similar to Ansys-"Operating Pressure" for pressure but I don't know about the velocity. Or are they the same as "Reference Values" in ...

Re: ALE method and Internal Coupling Problem

I don't understand completely what you mean but from whatever I understood I think you meant outputing the values of fluid forces from Code Saturne as an array ofcourse and reading them,run Code Aster with it,The script for such maybe the one given below(I got it from Code Aster forum,someone who ch...

Re: Transient & Turbulent simulation fail with "Time Varying" time step option

Thank you Yvan,Scaling the model worked(also used least square method over extended cell neighborhood along with it) though I don't uderstand why as the code should take inputs and hence calculate rest.So conflict between mm and m should not be there right?Also sorry to say that the imposed presure ...

Re: Transient & Turbulent simulation fail with "Time Varying" time step option

Wanted to add something too.Is pseudosteady in any way applicable for transient flows in Code Saturne?Should I try that?

Re: Transient & Turbulent simulation fail with "Time Varying" time step option

I have tried with all three of options of "the least squares related" calculation method.None works. I am going to try the first two suggestions.But by extrusion do you mean a mesh extrusion?(imposed pressure outlet is not there,infact no option for the outlet at all after I turned the def...

Re: Imposed DIsplacement/Velocity confusion

Thanks again @Yvan Fournier.Truly grateful yet again for answering all my question as different topics.I would say this that I tried to find a solution by first searching them in the previous posts(which should be the norm) before giving you guys any pain.

Imposed DIsplacement/Velocity confusion

Hello, I wanted to know that does imposed displacement/velocity on the mesh walls or structure on which fluid forces act when used and the following added(source FSI Tutorial from CS Version 2): double precision xfor(3) Then, in the body of the subroutine, add the following source code: ! set the fo...

Here is the setup log too.Also the link to mesh that I used is given below.
