Question: "Error, (in pdsolve/numeric/xprofile)"


I am solving numerically a non-linear Pde using the command  "pds:=pdsolve(....)"  and all are as they should be...[ pds := module ()...] but when i am trying to plot the outcome i receive: "Error, (in pdsolve/numeric/xprofile) unable to compute solution for t>.188000000000000000:Newton iteration is not converging "

Is there a way to overcome this problem (even if i must lose in accuracy..)???




Please Wait...
