how to use the iterative solver for a physical model with large in size
Currently I am doing static structural analysis in ansys workbench. For my model i have to do mesh refinement study. Initially i have designed the model with 1.2L elements and slowly increased to 2.35L, the simulation was running successfully. When i increase the number of elements to 2.65L it was stopped due to memory issues. Can i use the iterative solver instead of direct solver. If so, how to use it and settings for that.
Anyone would be highly appreciated.
