Hi OpenFOAM users

I tried to compile the simpleMatrixTest.C located in /OpenFOAM/OpenFOAM-1.4/applications/test/simpleMatrix and it gives the following error:


singh@taifun:~/OpenFOAM/OpenFOAM-1.4/applications/test/simpleMatrix> wmake

I tried to look in the class but it didn't help me much.

Anybody expert in C++ please take a look and help me to understand what's wrong

Thanks a lot

I got the same error messages with the latest OF-1.4.1 versions (standard and dev). OF-1.3 worked OK.

Has anyone already fixed this problem with simpleMatrix....

Apparently, the matrix() function disappeared in the simpleMatrix class. The source() function is still there. I assume that simpleMatrix just works as follows

simpleMatrix<vector> A(2);
//filling the matrix
A[0][0] = 1.0;
A[0][1] = 2.0;
A[1][0] = 3.0;
A[1][1] = 4.0;

//Defining some source vector
A.source()[0] = vector(1.0, 1.0, 1.0);
A.source()[1] = vector(2.0, 2.0, 2.0);

//Solving the system
Info << A.solve() << endl;

Could someone confirm that this is the correct way?

Yup, what you are doing is fine. Have a look at simpleMatrix.H:

template<class>
class simpleMatrix
:
public scalarMatrix

Therefore simpleMatrix IS-A scalarMatrix and your access functions are fine.

Enjoy,

Do you mean that Ax=b, where A is the simplematrix, b is the source vector and x is the solution?
