Dear All

I have two functions, f and g . I want to get the minimum and maximum of two . How can I write it in OpenFOam

Thanks

hello

I think:

Code:

Info<< "min/max value   = " << min(f).value() << ", "
        <<  max(f).value() << endl;

Hi

I want compare two equations and the maximum should go into the function. How to write code for this in OF.

example : G = max (a/b , c/d)

Thanks in advance.

hi Kannan86

Have you solved this problem?

when i get the max of two fields, e.g. :
volScalarField fun = max(fun1,fun2);

compiling is OK, but when i run the code, the screan show the following error:
Arguments of max have different dimensions
dimensions : [0 0 1 0 0 0 0] and [0 0 1 0 0 0 0]

Thanks
