How to add multiple result types to a single subcase using Compose and writeh3ddata

Question

Hello mates!

I have a Compose script that processes data from an FE analysis. In the past, I used hwascii and hvtrans to compile the data into an H3D file. However, hvtrans becomes very slow for larger file sizes, so I want to switch to writing the data directly using writeh3ddata.

So far, this works: I can open an H3D file in append mode and create a datatype and a new subcase. The actual data is also written successfully.

What I’m struggling with is the creation of multiple result types for a newly created subcase. My goal is to create a subcase called "MySubcase" and then define two result types called "MyResultsA" and "MyResultsB".

How can this be achieved? The help page is not very encouraging, since it states the following for createh3dfile:

"append adds new information, but can't modify existing information. This means that you can't add datatypes, layers, or values to an existing subcase."

But surely it can’t be the case that a subcase can only have one result type.

Any help is appreciated!

Thanks in advance,

hi @QETU11235,

You can write multiple datatypes in a subcase if you first define all datatype IDs. Afterwards, you can define the subcase ID and loop through each datatype ID when using command writeh3ddata.
