Once a model was created and saved for the first time, SPRING automatically creates a dimensioning file name.dim.

The sizing is carried out "pseudo-variable". That is, a maximum number of nodes and elements is pre-defined. The larger this number, the longer take the necessary initialization routines in the model checking, even if the current project specifically requires only a fraction of the pre-defined maximum number of nodes and elements.

A clever sizing reduces the computational effort during the model checking. Is the selected sizing too small, the corresponding dimensioning variable in the dimensioning file can be changed with a simple text editor.

 

Example:

IDIM1 270000 = IDIM2

IDIM2 270000 maximum node-/element number

IDIM3 100000 max. number boundary nodes, fractures and single data

IDIM4 100000 max. number MATE,MARK,KTXT,ETXT

IDIM5 14 max. number 3d-layer

IDIM6 5110000 temporary field, 3d: ca. idim1 * 51 , 2d: ca. idim1 * 20

 

Meaning of the dimensioning variables:

Field	Meaning
IDIM1	maximum number of nodes/elements
IDIM2	maximum allowed node or element number
IDIM3	maximum number of boundary nodes, fractures and point-data values (i.e. potentials (POTE), in- and outflow at nodes (KNOT), concentrations (1KON), ...)
IDIM4	maximum number of values for material data (MATE), markings (MARK), node and element texts (KTXT, ETXT)
IDIM5	maximum number of 3D layers
IDIM6	dimension of a temporary field used during the optimization algorithm (3D models about IDIM1*51, 2D models about IDIM1*20)
