Default Structured to unstructured mesh problem

Hello everyone!
I have a problem while saving my ICEM CFD mesh. When I click "Save" or just close the ICEM application (it saves before exiting) the structured mesh I've been working on automatically converts to unstructured.
Is there a way to "unconvert" the mesh somehow back to the structured one or stop ICEM CFD from converting it to unstructured while saving/quitting?
I hope for your help very much, because currently, ICEM is winning 7:0 in messed up projects of mine.

For which solver will you use your mesh?

For ANSYS, but I want to save the mesh for the further corrections, etc.

I mean cfx or fluent.

But what do you mean by saving? By saving the project or exporting it to a solver (e.g. cfx or fluent)?

To my best knowledge these are unstructured solvers so you can make a structured mesh, the solver uses it as an unstructured mesh anyway.
If you want an export to something structured you should export to a (ancient) structured solver e.g. cfx-4 or star-cd.

Good luck, Gert-Jan

I wanted to mention Fluent, my bad. Yes, I want to save the project (or close it) but I want to be able to come back to it later for some mesh adjustments and refinements. I know that I can convert it to unstructured before sending it to Fluent, but as far as I know I canít convert it back to structured to correct it.

Hi Grigory,

You only have to convert it back when you don't have the blocking. However this shouldn't be the case when you made the blocking yourself, right?

In case you have a mesh but no blocking, you can find an option to resonstruct a blocking from a given mesh, if and only if it was created structuredly. Go to File> Blocking > Create from Unstruct Mesh

Be warned, his feature can take quite some time to reconstruct a big mesh!



But back to you original question, you could try to close your mesh(File>Mesh>close Mesh) before saving the project.



Best regards,
Sebastian
