Elmer+Paraview

To whom it may concern I am new to Elmer. I want to model the gas flow by the pressure difference in the tube. I want to use the Perfect Gas model in Elmer. But I faced errors when I used the Perfect Gas model. I would be pleased if you help with this issue. I attached my SIF file for your reference...

Re: Variable boundary condition execution

Hello,
Thank you for your response.
How can I make the pressure and heat flux boundary condition variables? I need to have a variable pressure and Hear flux in my modeling

Re: Variable boundary condition execution

Hello
Thank you for your response.
So, how can I use the Dirichlet boundary condition variable? I need to set the heat flux variable of velocity 3. Temperature is a Dirichlet boundary condition, If I remove constant temperature, So, I can use Hat flux as a variable of velocity?

Re: Variable boundary condition execution

What do you mean? Should I remove the temperature in the Dirichlet boundary condition? What should I do in Pressure boundary condition?

Re: Variable boundary condition execution

Dear Peter I would be pleased if you give me some advice about how to change the Dirichlet boundary condition from constant to a variable? I have two variable boundary conditions the first one is heat flux that is variable of velocity 3 and the second one is pressure 3 that is available of temperatu...

Re: Variable boundary condition execution

Hi Peter
Thank you for your response, How can I change it to the variable? I am new in Elmer and I don't know How can I fix it.
I appreciate the time that you spend on my modeling
sincerely,
Armaghan

Re: Variable boundary condition execution

Dear Peter The modeling run without any errors. But when I made changes in variable boundary conditions, the results in Paraview and convergence diagram were constant. I think that is because of the boundary condition didn't execute in modeling. for example, when I removed the variable boundary cond...

Dear Peter I double checked the quotation marks and still I have a same problem. The variable boundary condition doesn't execute. I write the corrected SIF file for your reference. Header CHECK KEYWORDS Warn Mesh DB "." "." Include Path "" Results Directory ""...
