Don456 New Member Felix Apel Join Date: Sep 2009 Posts: 15 Rep Power: 17	Hi, I'm currently working on linear equation solvers on GPU's using Java. I have working versions of CG and BiCGStab in Java and Cuda with a quite nice speedup when Cuda is used(depending on the size of the equation system). If you want to know more about it let me know. For validation I have written a small program to solve the diffusion-convection equation(one dimensional) with finite differences as stated in Fertziger, Peric. It works quite well but if I try to increase the number of grid points higher than 100, the equation system is not converging anymore. Has anyone suggestions regarding this? Greetings Felix
