Data definition in QuickField means assignment of the physical properties to the labels used for main groups of geometry primitives - edges, blocks, or vertices. Each of them may be edited by the same approach using the Data Editor. Data files are specific to the problem type, but data presentation and all operations are very similar.
You can specify a boundary condition or a field source as a function of time or coordinates. QuickField introduces formulas allowing to enter formula-defined field values instead of constant numerical values. You can also specify non-linear materials.
To convert problem data from QuickField proprietary format to MS Excel tables and back you may use our free utility QuickField to Excel data converter.
