[Paraview] Paraview Vtu to Exodus. Single block, multi element?

[Moreland, Kenneth]

Andi,

You said you need an output with multiple blocks, but your last comment, “I need 1 block data set with 2 or more element data inside it,” suggests that what you really need is to add a second field of data.

Try using the calculator to add that second field. Set the attribute mode to “Cell Data”, the “Result Array Name” to “Dummy”, and the Expression to 0. Now when you write that out to an Exodus file you should have two element data fields: the original tetrahedral rank and the Dummy field you created.

Subject: [EXTERNAL] [Paraview] Paraview Vtu to Exodus. Single block, multi element?

Hi all, i need help please.

Introduction:
My problem is that I need to convert a vtu file into an exodus formatted file that reads several element block data.
When I load my data in vtu, all i see is a white cubic block.
This block has 2 data arrays named tetrahedra rank and tetrahedra number. When I change my coloring to tetrahedra rank, I can see 2 colors red and blue coloring my block.

I want to save the vtu file into an exodus format file and load it to another software but the other software only shows me the output of colors if there are several element blocks.
 In my case, the vtu file converted to exodus has only 1 element block.
In paraview, I can go properties, add the variables of tetrahedra rank and then change coloring then i see what i want to see.
But in the software I am supposed to load the data, I can't do that.
Im supposed to make my exodus data into 2 or more element blocks and then load it in that software which makes the software goes "ok so there are various data ! lets color it".

I don't know what should i do to change my vtu file with cell data of tetrahedra rank clearly showing the 2 data sets into 2 element blocks.
I have tried to use edit> find data> extract selection > repeat for the next > group the data.
I get a multi block data set. It didn't work. I need 1 block data set with 2 or more element data inside it.

Please help,
Andi
