Min. element angle

Minimum angle, which the individual mesh elements (finite elements) area is allowed to have. This value should not be too small (physical reasons) and should not be too big (because otherwise mesh generation is not possible).

Max. element size

Maximum permitted size for a mesh element (finite element). This number is a ratio that is relevant to the size (maximum measurement of the circumscribing rectangle).

Max. rel. changes

The calculation of temperature dependent conductivity values will continue until either the relative change of the conductivity value of all domains with temperature dependent conductivities are smaller than the maximal tolerated relative change, or the maximum number of iterations has been reached.

Max. No. iterations

Determines the maximum number of iterations (for the calculation of temperatures dependent conductivities, the system equation solver as well as the automatic mesh refinement).

Max. rel. error: 10 E -

Determines the maximum relative error of the solution vector. The resulting system equation will be solved iteratively until the relative error is less than this value, or until the maximum number of iterations has been reached.

Activate

If this option is active, then the element mesh will automatically be refined at those places, where the relative error of the current solution is greater than the critical limit. The mesh refinement persists until the relative error in all places is less than critical value or until the maximum number of iterations has been reached.
