solut

function solut(x,y,iderv,t) is provided to evaluate the computed solution or its derivatives at any point in the domain. The parameters are:

real x,y (input) The point at which to evaluate the solution.

integer iderv (input) Which derivative of the solution to evaluate:

1 --

2 --

3 --

4 --

5 --

6 -- U

integer t (input and output) On input, t should be a guess of which triangle the point is in. If you do not know, then set it equal to 1 for the first call, and use the returned value for subsequent calls. On output, t is the triangle the point is in.

A second version of solut is provided for evaluating solutions that have been saved using the save/restore procedures (see section 7.3). The saved-solution evaluation is performed by function ssolut(x,y,iderv,t,rwrk,iwrk) where x, y, iderv and t are as above, and rwrk and iwrk contain the saved state, as in section 7.3.
