- - List of plane (https://www.cfd-online.com/Forums/openfoam-programming-development/96765-list-plane.html)

Hi Everyone,

i want to create a list of planes

==>

Code:



    vector n (0, 0, 1);

    

    point d (0.25,0.25,0.25);    

    

        plane cutPlane(d,n);

    scalar a(1);



    List<plane> b;



    b.append(cutPlane);

but the compiler yells at me:

Code:

make: *** [Make/linuxGccDPOpt/volFoam.o] Fehler 1

but the list works fine i write

Code:

    scalar a(1);



    List<scalar> b;



    b.append(a);

Thank you for your help

Best regards

The plane is missing an empty constructor, just add

Code:

plane() {};

in the public interface part of the class plane, or better yet, check out the latest version of OpenFOAM-1.6-ext (if this is what you are on), it has been fixed in the meantime, and compile the library only.

Code:

error: no matching function for call to ‘Foam::plane::plane()’

Means: I really need the function (constructor) plane(), but I can't find one.

Now, tell me, what are you using this for? :)

i want to create the class cellcuts. For that i need the list of plane for the consructor.

In the end i want to calculate the volume of the cell cutted by the plane.

Thank you for the quick response

im trying to change plane.C and plane.H

Did you manage to figure out how to define a object of "class plane"??

Use PtrList<plane>.

Code:

const point& p1=vector(0,0,0 );

const point& p2=vector(0,0,10 );

const point& p3=vector(0,0,20 );



PtrList<plane> Myplane(p1,p2,p3);

where is mistake?

Code:

PtrList<plane> planes(3);



planes.set(0, new plane(point(0,0,0)));

planes.set(1, new plane(point(0,0,10)));

planes.set(2, new plane(point(0,0,20)));

Good luck!

planes.set(2, new plane(point(0,0,20)));

Good luck!

Code:

error: ‘plane’ was not declared in this scope

And another code

Code:

point xyz(0,0,0) ;// choose the point through which //the plane goes



vector dir(0,0,1) ;// normal direction

plane plane1(xyz,dir);



cuttingPlane plane1(mesh, plane1);

gives an error:
