SOLVESTAT Solve stationary problem.

[ U ] = SOLVESTAT( PROB, VARARGIN ) Solves the stationary problem described in the PROB finite element struct. Accepts the following property/value pairs.

Input       Value/{Default}              Description
nsolve scalar/{1} Non-linear solution method
1 = Fixed point (Picard) iteration 2 = Newton method <0 = |nsolve|-Picard steps before Newton
jac scalar/struct {0} Newton Jacobian computation type
. - Direct assembly using symbolic jac. form and jac.coef struct contents 0 - Assembly by numerical differentiation minnit scalar/{0} Minimum number of non-linear iterations maxnit scalar/{25} Maximum number of non-linear iterations nlrlx scalar/string/{1.0} Relaxation between non-linear iterations, scalar or string expr. ex 0.5*(1+(it>5)) nlinasm logical/{[0 0 0]} Force non-linear reassembly of A, f, bdrn toldef scalar/{1e-6} Stopping criteria for solution defects tolchg scalar/{1e-6} Stopping criteria for solution changes reldef logical/{0} Check relative defect changes relchg logical/{1} Check relative solution changes init u0|{expr}/{0} Initial value solution or experession solcomp {all dvars} Dep. variables/subdomains to solve for icub scalar/{2} Cubature rule/order used in assembly isymm scalar/{0} Symmetrize BCs if applicable waitbar scalar/{0} Show waitbar fid scalar/{1} File identifier for output ([]=no output)
