Re: [Paraview] Animating a function of a field

2017-01-04 Thread Cory Quammen
Aleksejs,

The following should work:

* add a Programmable Filter to the source that produces the
unstructured grid with f and g. Set the Script property to

data = self.GetOutput()
data.ShallowCopy(self.GetInput())

and the RequestInformation Script to

timeSteps = range(100)
outInfo = self.GetOutputInformation(0)

timeRange = [timeSteps[0], timeSteps[-1]]
outInfo.Set(vtk.vtkStreamingDemandDrivenPipeline.TIME_RANGE(), timeRange, 2)
outInfo.Set(vtk.vtkStreamingDemandDrivenPipeline.TIME_STEPS(),
timeSteps, len(timeSteps))

You can change timeSteps to whatever values you want the time variable
to take on.

* Add a Python Calculator to the Programmable Filter, and set the expression to

f * sin(t_value) + g * cos(t_value)

Optionally change the "Array Name" property to "h". You can then
visualize the h field however you wish.

Hope that helps,
Cory

Re: [Paraview] Animating a function of a field

Aleksejs,

Using brute strength and awkwardness, three conditions are needed:

(1) if your datum set is defined as f(x,y,z,t) & g(x,y,z,t),

(2) if both f(.) and g(.) are either cell values or point values, and

(3) if the variable 'time(.)' has been explicitly added as a datum set 
item (a name and a value),


then add PV's Calculator Filter to the pipeline where 'results' is 
replaced by 'h' and the equation is set as f*sin(time)+g*cos(time).


After selecting the 'APPLY' button, 'h(.) will be added to your datum-set.

(To the best my knowledge, 'time' is not available in the PV Calculator 
filter.)

Dear Paraview,

I have a 3d unstructured mesh with two fields defined over it - f(x,y,z) and

I want to create a movie of a following function

h(t) = f * sin(t) + g * cos(t)

where t is time. How would you do it?

[Paraview] Animating a function of a field

2017-01-03 Thread Aleksejs Fomins
Dear Paraview,

I have a 3d unstructured mesh with two fields defined over it - f(x,y,z) and 
g(x,y,z)
I want to create a movie of a following function

h(t) = f * sin(t) + g * cos(t)

where t is time. How would you do it?
