I am new both to Paraview and LS-Dyna, so I apologize if this is a stupid question. I can open my d3plot files in Paraview without problems and visualize some quantities such as Stress. But I can’t see strains. On the other hand, in LS-PrePost I can see all the strains and even principal strains. What would be a good way of gaining full access to the full d3plot file in Paraview?

Export your model file from LS-DYNA into a format that Paraview can load (e.g. Nastran BDF) and then the simplest way to handle the result sets would be to export them into CSV files.

> Harald, Here is the state file [merge\_arrays\_state.pvsm](https://discourse.paraview.org/uploads/default/original/2X/d/def04e40c56d8482785e3a3b5575d80bc78fbf26.pvsm) (251.2 KB) Here’s what I did, I opened the two files then selected the .nas and .csv readers in the pipeline browser and then created the Programmable Filter with the following script: blk0 = output.GetBlock(0) tbl = inputs[1] blk0.GetCellData().PassData(tbl.GetRowData().VTKObject) The result is that all the arrays from the csv are now available on the cells.
