Hello everyone!

I am new to Freefem. I am using P2b elements in my simulation. I want to export the data and plot the field in another software. However, Matlab and Paraview do not support such type of element.  
Is there a software or a way that is available for post-processing with P2b elements？

Thank you in advance!

I’m not aware of one, but you can follow the approach suggested here in [this post](https://community.freefem.org/t/supporting-higher-order-elements-in-iovtk/1302/2) to get a workable process in Paraview.
