CUPyDO interface

CUPyDO interface

The python file driving the CUPyDO computation consists in two functions: the first contains a list (python dictionary) of parameters used to initialize the interface, while the second runs the actual computations.

Parameters definition

    # Configuration files
    p['cfdFile'] = string # path to fluid cfg file 
    p['csdFile'] = string # path to solid cfg file'

    # FSI objects
    p['interpolator'] = string # interpolator type available: Matching, RBF, TPS
    p['criterion'] = string # convergence criterion available: Displacements
    p['algorithm'] = string # FSI algorithms available: Explicit, StaticBGS, AitkenBGS, IQN_ILS

    p['nSteps'] = int # number of time steps to keep
    # needed by RBF interpolator
    p['rbfRadius'] = double # radius of interpolation for RBF
    # optional for RBF/TPS interpolators
    p['interpOpts'] # optional options for interpolator, [0] = max number of iterations, [1] = preconditionner type
