How to print the cell value row wise?
 
1 Attachment(s)
Hello everyone,

I want to print the volume fraction values (alpha) of each cell and print them in row wise. As fur as I know Openfoam calculates the whole domain during each iteration. But I want to have the values of 0.078x0.06 portion of the domain only during my simulation.

Something in C programming like...

Code:


for (i=0; i<0.078; i++)
{
 for (j=0; j<0.06; j++)
  {
        printf("%f ", alpha[j]);
  }
printf("\n");
}

Thank you

Can you please specify what you mean. Do you want OpenFOAM to only calculate a certain region of the domain at each time step? Or do you want the values in a certain region be printed to the terminal? Or something else?

Thank you for your reply.

Actually I want the second case that you have mentioned. I want the values of a certain region, specifically for the area 0.078x0.06 for post processing only.

You can define a probe in each of the cells to get time histories of your alpha.

Thank you for your reply.

Can you please explain a bit more on how to implement it?
