Re: Compute or store the CRS matrices

It appears that we get triples like (i,j, value) type when using your suggestion. This is for the output of the A-matrix in linsys_a.dat This is not CRS but good for own cross checks. Is this the ListMatrix format type?

Thanks K Batra

Re: Compute or store the CRS matrices

Thanks Kevin for your efforts. Really appreciate it. In the mean time I worked as well and please have a look at mine (seems worked) ! Call SaveCRSMatrix to save the CRS matrix information CALL SaveCRSMatrix(Solver % Matrix, 'matrix_output.txt') !-----------------------------------------------------...

Re: Compute or store the CRS matrices

Good evening, Just an update that I tried to make some modifications in the VectorHelmholtz.F90 (see attached) in order to save the CRS matrix. It complies well and provides VectorHelmholtz.so and vectorhelmholtzutils.mod binary files. But later when I execute ElmerSolver case.sif, it crashes and re...

Compute or store the CRS matrices

Greetings, I am writing to seek your assistance in computing and storing the CRS matrices. I have successfully run a waveguide problem, compiled the vectorhelmholtz.f90 file, executed the .sif file, and visualized the vtu file in ParaView. Now, I would like to learn how to extract the CRS matrices f...

Re: Wave Propagation in Bent Waveguide - VectorHelmholtz

Hello again, Thanks for your answers. I really appreciate it. I was able to solve the problem with one box :) Now I extend the problem and added two more boxes to create a channel. Unfortunately this time I can't visualize the electric field/Poynting vector moving further. I hope you can identify th...

Re: Wave Propagation in Bent Waveguide - VectorHelmholtz

Thanks Peter for pointing out. My intent is to have dimensions i.e. a= 10 cm and b= 5 cm.
