The CFX-Solver Manager is a graphical user interface used to: Define a run Control the CFX-Solver interactively View information about the emerging solution Export data Solver Manager Define a new Solver run Solver Input File should be the .def file Can also pick .res, .bak or _full.trn files to restart a previous incomplete run To make a physics change and restart a solution, create a new .def file and provide it as the Solver Input File then select the .res, .bak or _full.trn file in the Initial Values Specification section If both files have the same physics, this is the same as picking the .res/.bak/_full.trn file as the input file Use Mesh From selects which mesh to use. If the meshes are identical can use either option, otherwise: If you use the Solver Input File mesh, the Initial Values solution is interpolated onto the input file If you use the Initial Values mesh only the physics from the Solver Input File is used Continue History From carriers over convergence history and iteration counters Solver Manager – Defining a Run Solver Manager – Defining a Parallel Run By default the Solver will run in serial A single solver process runs on the local machine Set the Run Mode to one of the parallel options to make use of multiple cores/processors Requires parallel licenses Allows you to divide a large CFD problem into smaller partitions Faster solution times Solve larger problems by making use of memory (RAM) on multiple machines The Local Parallel options should be used when running on a single machine The Distributed Parallel options should be used when running across multiple machines Serial Local Parallel Distributed Parallel Different communication methods are available (MPICH2, HP MPI, PVM) See documentation “When To Use MPI or PVM” for more details, but HP MPI is recommended in most cases Solver Manager – Defining a Parallel Run The Show Advanced Control toggle enables the Partitioner, Solver and Interpolator tabs On the Partitioner tab y
