Several smoothed results

Post by vpapanik »

Hello ! Is there a reason why several smoothed contour results cannot be shown at the same time ? Simple contours work perfectly.

Do you mean Window->Several results...
'one over another'
and draw several contour fill results?

Usually draw more than a contour fill result doesn't has sense, because they are drawing on the same support and they are overlapped!!
several results is interesting for example to draw a contour fill (e.g. a pressure scalar field) and simultaneously over them a vector result (e.g. a velocity field)

Actually my model includes both quadrilateral and triangular elements which import results from different .res blocks. So it is meaningful to show e.g. stress contour for all element types at once. This works using

however, smoothed results are not shown, and secondly, several results are not supported when creating animations.

The reason is the internal programming structure in postprocess: Triangles and quadrilaterals have two different 'gauss points' definition, and each 'elemental (on gauss points) result' is related to a gauss point definition, then a property must be written 'on gauss points' as two different results and GiD usually operates in a single current result. (view several results is a trick to allow to see more than one result simultaneously in screen).

We will to enhance it in the future, to allow somehow consider this two results (only because of use differnt 'gauss points') as 'the same result'

If do you write a nodal result instead of two elemental results (one by trias and other by quads) then you don't have this problem (and you exacly decide how the elemental values are extrapolated to the nodes and averaged between neighbor elements to show a 'smoothed continuous result')
