Introduction

This page documents the contents of a SIESTA namelist input file. SIESTA namelist variables are defined in the siesta_info common block.

`l_silo3D`	Produce silo 3D output.	siesta_namelist::l_silo3d
`l_output_alliter`	Write output files on all iterations instead of only iterations that lower the MHD energy and force residuals.	siesta_namelist::l_output_alliter
`l_VMEC_Uniform`	UNKNOWN	siesta_namelist::l_vmec_uniform
`lasym`	Use non stellarator symmetric terms.	shared_data::lasym

`niter`	Maximum number of iterations after diagonal prec.	siesta_namelist::niter
`ftol`	Minimum force tolarance for converged solution.	siesta_namelist::ftol
`mupar`	Resistivity factor.	hessian::mupar
`levmarq_param`	Inital value of Levenberg-Marquardt parameter.	hessian::levmarq_param
`eta_factor`	Resistivity value.	siesta_namelist::eta_factor
`nprecon`	Skip diagonal preconditioner if greater than zero.	siesta_namelist::nprecon
`ngmres_type`	Preconditioner type.	shared_data::ngmres_type
