Solution Settings (SimSolid)

Adjust solution settings to refine SimSolid Solutions.

SimSolid employs a proprietary adaptive technology to automatically refine the solution in the areas where it is necessary to achieve the highest accuracy. Multiple solution passes are performed and with each pass, accuracy measures are created, and equations are enriched locally as required. The only settings specified manually are the maximum number of solution passes along with a small set of optional settings.

Settings can be applied globally to the entire assembly or locally to individual groups of parts. This allows you to first determine the overall system response, then quickly drill-in to specific areas of interest.

The settings are specified independently for each analysis. This provides a convenient method to do analysis comparison and solution convergence studies.

To adjust settings for all load cases, click the Solution Settings tab on the Structural or Modal guide panel.


Adaption	Procedure
Global	Select the Global option. Best for general load path prediction, modes and/or thermal analysis. Uses 3 adaptive passes, Adapt to Thin Solids and global adaption. Refinement Level is set to Standard. Typically the fastest solution method.
Global + Local	Select the Global + Local option. Best for stress calculation with more precision. Uses 4 adaptive passes, Adapt to Features, and Adapt to Thin Solids. Automatically creates local group for the parts and groups based on its relative volume. Part volume grouping is automatically done based on the total volume of the assembly. The parts that account for the 10 percent of the total volume are grouped together. For example, the top 10 percent go into group 1, 10-20 percent in group 2 and so on. Refinement Level is set to Standard.
Custom	Select the Global + Local option and adjust settings as needed. Define the max number of adaptive solution passes. This rarely needs to be more than 6. Click Create to create a new parts group. Select the Parts collector and click the parts you want to include in the group. Optional: Select the Adapt to Features check box for each group to adapt for local features for structural and nonlinear statistics. Optional: Select the Adapt to Thin Solids check box for each group to adapt for thin, curved solid sections. Apply locally on a part-by-part basis. Optional: Refinement Level can be set manually among three options for each group: Standard, Increased, and High. To discard custom settings and use the default Global + Local settings, click Restore Defaults.
