I implemented Conjugate Gradient solver which solves the linear system of the form Ax=b. So I implemented new sparse storage format i.e. Compressed Sparse Vector(CSV). Now I want to integrate this developed CG solver in OpenFOAM. Is there any other library than Paralution? Because Paralution uses LDU decomposition ,which cannot be used for CSV format. If not I want to implement this CSV format to paralution library. So please suggest me the way I can do this.
Thank you sir for replying…I refered to BCSR interface.. But for converting matrix to CSV ,first I need to get the original matrix… if I use import_openfoam_matrix() function ,it directly converts the ldu matrix to CSR and returns..
