Increasing max linear solver iterations in HyperworksCFD
I would like to increase the maximum number of iterations for the temperature and radiation equations. (Log files attached)
I tried to set this in the UI for Hyperworks CFD but it seems there are no fields for this to be filled in for radiation.
I then tried to fill this in the input file by using the acuTrans commands. (Input file attached)
# +----------------------------------------------------------------------+ # | Time Integration | # +----------------------------------------------------------------------+ TIME_INTEGRATION { initialize_stokes = on initialize_turbulence = on } STAGGER( "temperature" ) { num_krylov_vectors = 20 min_stagger_iterations = 2 max_stagger_iterations = 4 min_linear_solver_iterations = 10 max_linear_solver_iterations = 4000 } STAGGER( "radiation" ) { equation = radiation min_stagger_iterations = 2 max_stagger_iterations = 4 convergence_tolerance = 1.e-3 lhs_update_frequency = 1 linear_solver = gmres min_linear_solver_iterations = 10 max_linear_solver_iterations = 4000 num_krylov_vectors = 40 linear_solver_tolerance = 0.01 projection = on } LINEAR_SOLVER_PARAMETERS { num_radiation_projection_vectors = 5 }
Problem is, when i run this in Compute Console, i get this;
