Single and double derivative of variables

[Kenichiro-Yoshimi (Kyoshimi)]

VMTK is difficult to use within ParaView because pip installation is no longer supported. It should be possible to use it as a Python program within an Anaconda environment. Please refer to the link below.

Calculating double derivatives options

Calculating higher-order precision gradients using vmtk’s vtkvmtkUnstructuredGridGradientFilter in Python is relatively straightforward. For an Anaconda environment, first create a virtual environment and install vmtk using the following commands: conda create -n vmtk python=3.11 conda activate vmtk conda install conda-forge::vmtk Next, you can create a Hessian matrix by applying vtkvmtkUnstructuredGridGradientFilter twice to a variable with a Python program like the one below. However, this …
