Hi...

I am trying to get the area average of pressure in a section of the duct.

What I am doing right now...

1. Collect the cells

2. Create shells on the face of the cells

3. getc p - to get the pressure values for these cells

4. summ cset - to get the average values

5. oper getc area 5- to get the areas into register 5

Problem

In the post registers, when the pressure is non zero, the area is zero and vice versa. The product of the two columns is always zero.

Am I missing any vital steps in the process?

Regards

Radhika

Hi Ben

I did create shells on the face that I needed the average.

I am a little confused about the parameters for the pmap command though. Can you help me with that please.

Or is there a GUI method to do pmap.

Regards

Radhika

Hi, why don't you use the INTEGRATE command. It will give yo the summ of p times A, and the summ of A Iy you divide both values you will get the Area Averaged pressure.
