1). one non linear (pde)
Please separate the above into conservative flux, source term, damping or mass coefficient, mass coefficient

where w is m,n,h
in which part should i declare these ode's
please check dat the procedures which i hav followed is correct or not.
3) In V 3.5a we hav UMFPACK (direct solver but i could'nt locate it in v 4.0a
