ODESOLVE error
ODESOLVE error
(OP)
Hi,
I am beginner in MATHCAD and I want to define an ODESOLVE matrix , but i get an error telling that i dint define the initial conditions.. but the error is actually not that.. could someone please help me with this issue..? Please check the attached MATHCAD file..

Without getting too deeply into it, what is "Phi"? - first row after "Given"

It is the heavyside step function (to switch functions).. but I don't think that's the problem..

Third equation: C.m(t) and C.s(t) should be replaced by C.m and C.s
Last equation: There is a typo between the last parenthesis and the P.N. There is a tiny decimal point inbetween which would be interporeted as multiplication by 0 - not intended, I guess.
Nevertheless the system will still fail with (as usual in solve blocks in general) a not much helpful error message.
I don't think that the Heaviside function will cause the problem. The factor phi is zero anyway so it would have no effect. If you replace it by any constant, the system will still fail.

but then the system is not completely correct with its calculations.. I have to check with the math part anyways...
