code_saturne User's Forum

Dear experts,

Hello. I'm using version 7.0, trying to use LES data on a 2D slice to do Proper Orthogonal Decomposition. But since I need data of many timesteps, the disc space requirement is huge. So I want to save results only on one slice, rather than save results in the whole domain. Could you suggest if this is possible and how to do it?

Thank you very much in advance for any help.

Best regards,
Ruonan

Hello,

For this, there are some advanced use postprocessing r examples, making use of MEDCoupling.

Another approach is to project data on a 2D Cartesian Grid (or simply use an unstructured mesgh slice) under ParaView, and use Catalyst to record this as the code computes.

Both cases require a code_saturne installation with some optional libraries. Otherwise you can roll your own filtering with advanced user postprocessing, with sunsets of the main mesh.

Best regards,

Yvan
