void Solution::assign ( Solution * sln )

void Solution::enable_transform ( bool enable )

Enables or disables transformation of the solution derivatives (H1 case) or values (vector (Hcurl) case). This means FN_DX_0 and FN_DY_0 or FN_VAL_0 and FN_VAL_1 will or will not be returned premultiplied by the reference mapping matrix. The default is enabled (true).

void Solution::free ( ) [virtual]

Frees all precalculated tables.

Implements Function< TYPE >.

order3_t Solution::get_order ( ) [virtual]

Returns:: Order of the function on the active element

void Solution::set_active_element ( Element * e ) [virtual]

Called by the assembling procedure and by other functions. In PrecalcShapeset it sets an internal variable that can be later retrieved by get_active_element(). In Solution it selects the element to retrieve solution values for, etc.

Parameters:

[in] e - Element associated with the function being represented by the class.

Reimplemented from MeshFunction.
