Re: [Paraview] Animating a function of a field
Dear Cory, It seems to work quite nicely. Thank you!!!

Re: [Paraview] Animating a function of a field
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.

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.)

[Paraview] Animating a function of a field
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.
