defining geometry in pdetool

Can anyone suggest me how to generate a complex geometries other than those defined already in pdetool. I tried using pdepoly with the coordinates of the geometry as arguments. But it gives "Geometry error"

The coordinates I used are [0.0001 0 0 0 0 1.00E-06 2.51E-06 9.76E-07 8.07E-06 9.26E-07 1.59E-05 8.66E-07 2.50E-05 8.13E-07 3.41E-05 7.75E-07 4.19E-05 7.57E-07 4.75E-05 7.51E-07 5.00E-05 7.50E-07 5.25E-05 7.51E-07 5.81E-05 7.57E-07 6.59E-05 7.75E-07 7.50E-05 8.13E-07 8.41E-05 8.66E-07 9.19E-05 9.26E-07 9.75E-05 9.76E-07 0.0001 1.00E-06 ]

Can some one tell me what the problem is?

Thanks Dileesh

The above just generates a vector of numbers, what are your co-ordinates exactly?

That data was in csv format.. The real data is

x_coordinate= [0.0001 0 0 2.51E-06 8.07E-06 1.59E-05 2.50E-05 3.41E-05 4.19E-05 4.75E-05 5.00E-05 5.25E-05 5.81E-05 6.59E-05 7.50E-05 8.41E-05 9.19E-05 9.75E-05 0.0001 ]

Corresponding y_coordinate=[0 0 1.00E-06 9.76E-07 9.26E-07 8.66E-07 8.13E-07 7.75E-07 7.57E-07 7.51E-07 7.50E-07 7.51E-07 7.57E-07 7.75E-07 8.13E-07 8.66E-07 9.26E-07 9.76E-07 1.00E-06 ]

And this data is supposed to generate a domain with three straight edges and fourth edge is a parabola.

Do you have more than one geometry? I am able to execute pdepoly with your data and it works fine.

Could you paste the 'exact' error message you see on the command line?

Also check if this is relevant to you:
