I am working with a small 2-D (x-z) finite element code for fluid dynamics modelling over ocean topography on my pc.

(I have full control on output data formats).

I am looking for a plotting package to produce some plots.

The only plots I want to make are the following:

1) vector plots for flow current

2) contour plots for turbulence or fluid density

3) both vector and contour together

and of course there will need to be an outline of the bottom ocean topography.

The finite element mesh I am using consists of 9-noded quadrilaterals (4 nodes at the corners, 4 nodes at the side centerpoints and 1 node in the center).

Sometimes the quadrilaterals are rectangular/square and in some regions they can be squashed so that they resemble a triangle (2 sides becomes linear with each other, but still a "quadrilateral" with 9 nodes).

I have been reading about tecplot and see that basic grids can be handled like the 4 noded quadrilateral.

I am interested to know are 9-noded quadrilaterals as I have described above able to be handled in tecplot?

You help is much appreciated.

Thankyou.
