I want to declare a vector, but the problem is that has the dimensions 1x106. So I cannot use NV_D because it is says that is to much arguments. Do you know how I can declare the vector instead?

 

Many thanks,

Have a look at the Documentation, vectors are defined like that, but you'll need to define each component.

Thank you very much for you message. I understand but then if I want to define an array. How I have to do it? because if I follow the documentation (there is not an example exactly what i want to do (I understand; https://www.sharcnet.ca/Software/Fluent6/html/udf/node248.htm). I got an error with the sintaxis. Sorry, the vector is not very well-looking but i needed since, each value of the vector will be the displacement value in the current time step (the simulation have 105 time steps).

 

Many thanks,
