Solver Products

Our expertise in technology and engineering has enabled us to create solver products that are used in multiple industries.

PCGLSS

PCGLSS is an iterative solver for solving Linear Systems arising in Finite Element Analysis. It is unmatched in its performance and capacity and is the market leader with an estimated user base of more than 70,000 users. It has been used to solve 3D problems with more than 7 million variables in about 10 minutes on a Desktop Personal Computer.

ITEREIGENSOLVE

ITEREIGENSOLVE is a Lanczos-based eigensolver for computing eigenvalues and eigenvectors of matrices arising in Finite Element Analysis. It is a high-performance eigensolver based on a combination of iterative and direct techniques.

VSDLSS

VSDLSS is a sparse direct solver for solving very sparse Linear Systems arising in VLSI circuit simulation. It is being used for Power Grid Analysis, Electromigration, and Signal Integrity. Our customers have used it to solve circuits with over 200 million nodes on an engineering work station.

SDSOLVE

SDSOLVE is a sparse direct solver for solving Linear Systems arising in Finite Element Modeling. It is best suited for solving problems with multiple load cases and for eigenvalue analysis.

HMSLSS

HMSLSS is an iterative solver for rapid solution of very large sparse Linear Systems with tens of millions of variables arising in Engineering Analysis and VLSI Simulation.
