Functionality of POD

[kowshiksri]

Hi Andre,

I was using the Flowtorch library to perform snapshot POD. After loading initial data and creating an instance of POD class, when I call on the _computedecomposition method it throws an error.

` 17 def compute_decomposition(self, mode="snapshot", solver="svd", device="cpu", precision="single"): 18 if mode == "snapshot": ---> 19 data_matrix = self._data.get_data_matrix() 20 if not data_matrix.device == device: 21 data_matrix.to(device=device)

AttributeError: 'Tensor' object has no attribute 'get_data_matrix'`

The data was passed as a tensor to the POD class, as expected by its constructor class.

I was also unable to find any implementation of the _get_datamatrix method. Is this functionality available? Can POD be performed using the given script?

Hi Kowshik, the POD class is just an experimental leftover from the initial development of flowtorch. Instead, use flowtorch.analysis.SVD. Have a look at this tutorial for a reference. Best, Andre

ok thank you
