Using Logical Operators (AND OR)

[Abdulrahman Almutairi]

Hi,

I was able to figure out how to use these logical operators, however, I am not sure if I am using them properly. Whenever I use them, the value of the parameter I specify ends up being 1 in the simulation.

For example, I'd assign the initial condition of a specie to be 10 for x<2, in the simulation the IC would be 1 instead of 10. 

I had noticed this for different types of parameters.

I am wondering if I am using the proper syntax? as I could not find any instructions on VCell or in the forum.

Hi Abdulrahman,

Did you use the following expression: 10*(x>2)

The expression x>2 evaluates to 1 wherever it is true and to 0 wherever it is false. Multiplying it by 10 should give you the result you want. If this doesn’t work, please provide more details, like a screenshot.

Best,

Les

Hi Les,

 

Thank you! I was not using that syntax. 

It works now.
