Hey,


I wrote a program that modified simpleFoam solver... Therefore I implemented some new header files... Now I would like to split my solver into two possible calculation methods. As a consequence I have some parameters which I read from an constant/InputData file for both variants and other parameter just for one or the other calculation... When I´m trying to split the input by if else statement, I run lots of "not declared in this scope" errors. Anny suggestions how to do this?


Here are some code snippets:


constant/InputData/

X    1;
A    A    [1 0 0 0 0 0 0]     1.0;
B    B    [1 0 0 0 0 0 0]     2.0;
C    C    [1 0 0 0 0 0 0]     3.0;

Programm:

createFields.H is calling #include "readInputData.H"

label X(readLabel(InputData.lookup("X")));


dimensionedScalar A(InputData.lookup("A"));
if(X==0)
{
    dimensionedScalar B(InputData.lookup("B"));
}
else if(X==1)
{
     dimensionedScalar C(InputData.lookup("C"));}

If I do it like this, the following program do not know the lookup data from B and C, leading to the above mentioned error.


Thanks in advance

This is because you are declaring the dimensioned scalars B & C inside the if/else statement. That means that when you leave the if/else statement, they go out of scope and are lost. You need to do it another way.

For example, you could use the value of X as the key for the item to read from the dictionary - eg "B" or "C". Then you do not need the if statement. Otherwise you need to declare the variables outside the if statement.

Thank you, I will try this out.
