Stress Analysis settings - Solver tab

Stress analysis solver settings are applicable to all simulations. When a new simulation starts, these preferences are used. You can override the global settings on a per simulation basis by changing the simulation properties.

This section discusses the controls on the Solver tab.

Solver Defaults
	Maximum Number of h Refinements	Sets the default number of h refinement steps for convergence. The default value is 0. Generally, it is best to keep this number below 5, with 3 or 4 being ideal. If the Stop Criteria is met, the solve process stops before the maximum number of refinements.
	Stop Criteria (%)	The refinement process stops when the selected simulation result returns consecutive values within the designated percentage. The default value is 10. Also, if the number of refinements is satisfied before the Stop Criteria is satisfied, the process stops.
	h Refinement threshold (0 to 1)	Specifies the default h refinement threshold for all new simulations. The value must be in the range of 0 through 1. 0 specifies all the elements in the set as candidates for refinement. 0 can be viewed as maximum refinement. 1 removes all elements in the set from refinement, thus no refinement occurs. The default value, .75, specifies that elements with equivalent errors at the top 25% are subject to refinements.
	Detect and Eliminate Rigid Body Modes	Specifies the default setting for all new simulations. Removes the rigid body modes in problems where not enough constraints are defined. However, they have a balanced load with a valid elasticity solution.
	Separate Stress Across Contact Surfaces	Specifies the default setting for all new simulations. Select to have explicit representation of discontinuous stress across the contact interface in the FEA formulation. Some components of the stresses can be discontinuous due to different materials of the contacting parts. Note: If you select this option, you deactivate averaging of results across contact surfaces.
Results
	Create OLE link to Result Files	Creates an OLE link to the result files. Unchecked, no OLE link is established. The setting applies to ALL simulations in the document.
