Backward Compatibility with Version 5.2

The new free quad meshing algorithm is used in new models, but for models created in earlier versions, the legacy algorithm is used instead. The default for the new method property is therefore auto in new models, and legacy52 in migrated models.

GeomInfo check() Method

The return value of the check() method in GeomInfo has been removed. Now, check() throws an error if the geometry is invalid.

The const Property in Solvers

The const property available for many solvers has been removed in version 5.2a and replaced with the cname and clist properties, which are string arrays for the constant names and corresponding constant values, respectively. For the node, the new property initparametersmethod, which can be set to "auto" (the default) or "manual", has been added to control automatic synchronization of values of parameters to use for initial expressions. The node now also includes the cname and clist properties.
