Hello mates,
I am trying to solve a system of Differential Algebraic equations using the daspk solver.
Running the script I get below error:
DASPK-- AT T (=R1) AND STEPSIZE H (=R2) THE
In above, R1 = 0.0000000000000D+00 R2 = 0.9633073903093D-11
DASPK-- ITERATION MATRIX IS SINGULAR.
error: daspk: the matrix of partial derivatives is singular (t = 0)
Any experience with above error would be highly appreciated.
I am not sure how I can proceed.
Thanks a lot!
Best,
Arash.
