Load simulation data

How you load data depends on the connection. The viewer looks the same afterward: a Source row in the scene tree, and fields in Rendering once they arrive.

Which control to use

See Cloud connection for why the preview stays on examples, and On-prem connection for your own files.

Files you can open

Open accepts VTK files only. A generic HDF5 file (.hdf, .h5) is rejected. If the data is VTK stored in HDF5, use .vtkhdf.

OpenUSD files (.usd, .usda, .usdc, .usdz) are what the server writes after conversion. They are not something you upload. If Open refuses a file, compare the extension with the table.

Open a file

1. Click Open at the top right.
2. Choose a .vtk, .vtkhdf, .vtp, or .vtu file.
3. Wait for conversion. Progress appears at the bottom of the sidebar as Cloud conversion or Local conversion.
4. The mesh appears, and Scene shows a Source row.
5. Scalar fields appear under Rendering after their names and ranges arrive.

Open adds another source to the current scene. New scene, in the same menu, clears that scene so you can start fresh. .vtp and .vtu are surface files. They open through the same steps as a volume.

Open an example

1. Confirm Infrastructure says Connected.
2. Click Examples at the top right.
3. Choose a card.
4. The example loads without an upload.

See Examples gallery.

Before you load

• Infrastructure should say Connected.
• On the cloud preview, sign in and use Examples.
• On-prem, follow the Docker setup in Infrastructure → Choose infra, then switch to On-prem and use Open or Examples. See On-prem connection.

Large files

• Conversion of a large VTKHDF file runs on the server. You can still move the camera. Leave the tab open until the progress card finishes.
• Examples are the faster way to learn the controls before a long upload.
• The machine where you finished the Docker setup must be reachable from the browser where you switch Infrastructure to On-prem.
