It is recommended for nonlinear problems and is well suited for ill-conditioned problems. The PCG solver (also known as the Power Solver) is an iterative conjugate gradient solver. It is the most robust iterative solver and is well suited for large, linear problems built from continuum elements.
14.06.2019 · the solver for my project (1Mio DOFs) is using the direct Sparse Matrix solver. But I have limited RAM and he is always going into out-core memory mode regarding to the solution output. Therefore I changed the Solver type to iterative and put the EQSLV, PCG command under the Static Structural branch.
The analysis can be a modal analysis using the PCG Lanczos method (MODOPT,LANPCG). Large deflection effects (NLGEOM,ON) are included. SOLID185 (brick shapes and KEYOPT (2) = 3 only) elements can be included. All other element types or other parts of the model that don’t meet the above criteria will be solved using global assembly (MSAVE,OFF).
• Sparse, PCG and ICCG solvers cover 95% of all ANSYS applications • Sparse solver is now default in most cases for robustness and efficiency reasons Solver Usage: Choices • Sparse direct solver ( BCSLIB ) • PCG solver (PowerSolver) • Frontal solver • …

Distributed ANSYS Restriction All equation solvers are supported in Distributed ANSYS. However, the SPARSE and PCG solvers are the only distributed solvers that ...
16.05.2012 · Ansys PCG Solver. fm756 (Aeronautics) (OP) 11 May 12 10:46. Hi, I currently using Ansys 13 APDL with the PCG Solver for a contact analysis. I am running multiple analysis that are writting over each other one after an other. Each time i'm extracting the important information and save them within a .txt file.
The use of iterative solvers in ANSYS took a dramatic step forward in 1995 in version 5.1. A new element based preconditioned conjugate gradient method (PCG) ...
