... the list shows that I replied twice, not true , only 1.
Click right on Odesove and see the two options:
fixed, adapt ... Odesolve is a numerical solver, it displays
the "lsplined numerical solution", therefore it it not an
export, i.e: it resides on the work sheet , solely.
In the attached example, we solve a 2nd order DE for
3 parameters [m = 1, 25, 50]. The two text box interpolate,
interpolate at ponit or collects a range of interpolated values.
You CAN'T naturally change the built-in lspline Odesolve.
On some project, you might want to see the other pspline,
cspline... There was complaints about that rigidity, here
it is solved: simple elegant . The trick is to pass the internal
vector of solution to a transit local loop. At this point, it is
easy to decide which spline you want to use. The other trick
is to pair the internal vector of solutions with a discretized
vector of the ranged integration variable .
In "S" we collect the 3 parameters [m = 1, 25, 50] solutions
You can collect as many as you want. The text box collects
the solutions you want as governed by the global definition 'j'.
Below, I have added the first and 2nd derivatives plots.
Whether it does help or not in your project, can't tell because
you had no work sheet attached, readable by Mathcad 11.
My point here is more than about solving the given DE, it is
essentially about using the advanced technique of using a
"local transit exploder". This same techique was posted
a day or two ago for collecting functions f(x,y) from a main
vector of user functions for plotting.

I hate that compobox, it should show a dummy vertical
dotted line about where my reply will appear once posted.
All that result from the indenting, a useless invention.
This PTC community is about dead on the number of Mathcad
discusions. Hopefully and for a while the webmaster
reads for all the comments and suggestions that now
have no place where to put them.
