I have a 2d look up table and I want to reach Cx value. Cx value is depends on AoA and mach variable values. AoA and mach numbers are from Table and it gives me Cx_alpha value. I can run and reach Cx_alpha without problem but I must multiply Cx_alpha and AoA to reach Cx value. What can I do for this?

By default, the "Product" block has two inputs. It's output is the multiplication of the two inputs.

What is Cx_alpha? It is not shown in the picture?

Add a product block with 2 inputs as Cx_alpha (your output) and AOA

Hi Merve,

As per my understanding, you want to know how to multiply a constant value with itself.

Consider the following block diagram:

The two inputs “AoA” & “mesh” are used to calculate “Cx_alpha”. To get the output “Cx”, the two parameters “AoA” & “Cx_alpha” are multiplied using a “Product” block.

For more information on the “Product” block, you can refer to the following documentation:
