<p dir="ltr">Hello, <br>
I need to slove a nonlinear problem :<br>
F(x)= 0 with x = xd specified on the boundary. I have setup an snes based solver. I need to modify it to handle the situation described below.<br></p>
<p dir="ltr">The bc value xd takes a set of values <br>
xd = {x1, x2 ......., xn}, xj > xi for j > i .</p>
<p dir="ltr">Parametrising xd(t)= x1 + (xn - x1) * t such that by selcting t between 0 and 1 I get all the xd values mentioned above. </p>
<p dir="ltr">I want the solver to automatically increase or decrease the t based on convergence criteria ( i.e., go back to earlier converged step and try again with a smaller step, ofcourse report divergence if the step size is smaller than a specified minimum step size) and solve system of equations. </p>
<p dir="ltr">Can I setup this problem as a TS ? </p>
