• the maximum level of the global error which will control the initial stepsize (half-value of the right-side of the inequality eq) and the computation time;

• the maximum level of the computation time; if the estimated computation time will overpass this value the computation of the approximate solution with the current method will be refused;

• the current method from the list of the available methods in the expert database for the given problem - this option is available only if the user stops the expert and force him to restart from a point to which the loading of the indicated method is started;

• the type of stepsize - a constant or nonconstant stepsize scheme, only in the case of a nonlinear problem.

Example for the system B1.
