Dear support,
I need to load a multi zone .encas file which is loaded as vtkMuktiBlockDataSet and after doing some manipulations I need to save it exactly in the same format. I can do it after using merge blocks to convert the data set from multiblock to unstructured grid to save it as .encas but I lose the information of the zones. Is there any way to achieve this?
Thank you in advance!

Iโm afraid the EnSight writer is not as capable as the EnSight reader in ParaView.
Unless you are able to use another format (like VTKHDF, Exodus, vtm), this is not possible yet in ParaView.

I understand. Is there any activity to improve this writter? I would be a great improvement for working in projects where this data format is mandatory ๐

I donโt think so but maybe @cory.quammen knows more.
If you are able to contribute, please reach out though!

I am not aware of any work to improve the EnSight writer.

I see, unfortunately I am not an experienced software developer since I have an aerospace engineering background. I would love to contribute in these tasks but I am afraid that my solutions might not be very efficient or well structured. But who knows, I have some ideas in mind for filters and I could experiment by implementing them within ParaView to gain experience there and become a contributor in the future.
Regarding the improvement of EnSight writer, it would be a very interesting area to work on since ANSYS Fluent is one of the most used CFD tools out there and the teams who use it rely typically on EnSight format to work and exchange data. However from someone like me who comes from a research background it is hard to leave behind ParaView just for not being able to export in EnSigh format as easy as it is to read files in this format. I hope that I am not talking selfishly but this is something that I see quite a lot around me ๐ฌ
It would be great to know if an activity to improve the EnSight writer is open! ๐
