2DSA Advanced Analysis Control

This dialog provides for definition of an analysis run with parameters not normally of interest to the typical user including use of band-forming centerpieces for Band sedimentation experiments. The advanced analysis choices presented in this dialog fall into three categories.

2DSA Advanced Controls

Functions:

Optimization Methods: Parameters in this section allow for methods beyond the default Uniform Grid method.

Simulation Parameters: Parameters here allow for changes in the base Lamm equation simulation computation method.

Standard Centerpiece	Check to specify a standard, non-band-forming standard 2-channel centerpiece
Band-forming Centerpiece	Check to specify a band-forming centerpiece if running a band forming sedimentation velocity experiment.
Band-loading volume (µL):	Specify the volume added to the reservoir in the band-forming centerpiece in microliters (µL).
Band-loading Volume:	Specify a band-loading volume value.
Simulation Points:	Specify the number of discretized radial positions used when numerically integrating the Lamm equation. For typical analyses, 200 simulation points provide sufficient resolution. Increasing this value improves the precision of the simulation but also increases computational time.
(mesh type)	Select from one of several mesh types, including Adaptive Space Time (ASTFEM), Claverie, Moving Hat, user File, or Adaptive Space Volume (ASVFEM).
(grid type):	Select the grid type to use in the simulation: MOVING, FIXED.

Refinement Options: These parameters duplicate some found in the standard analysis control dialog; and add the Regularization options

Model-Defined Grid
Model-Defined Ratios and Grid
Load Model	Load the model if Model-Defined grid or Model-Defined Ratios and Grid are selected.
Regularization
Regularization Factor:
