Pipeline for gradients ascent

1

Hi,

do you have a pipeline to compute gradients with the ascent plugin?

I tried the following but with no success

field-velocity = u, v
pipeline-grad = [{'type': 'gradient', 'field': 'velocity', 'output-name': 'gradvel'}]
scene-gradvel = {'type': 'pseudocolor',
                        'min-value': 0, 'max-value': 25, 'color-table_name': 'Cool to Warm',
                        'field': 'gradvel', 'pipeline': 'grad',
                    'render-1': {'image-name': 'gradvel/{t:4.10f}'}}

Best

In general you are better off using the gradients provided by PyFR. These will typically be more accurate than those computed by Ascent.

With that said I am unsure how your scene works as gradvel is a tensor (matrix). You probably need to add a magnitude somewhere.
