D3PLOT 22.1

File Formats Supported By D3PLOT

A list of the file formats supported by D3PLOT is given in LS-DYNA output files processed and Other output files processed.

Adaptively remeshed analysis filenames

D3PLOT supports LS-DYNA adaptive remeshing, in which a series of families are generated with a mesh that is progressively refined (see Section 4.2.5).

If the "base" <name>.ptf (or d3plot) file is selected then all successive families ( .ptfaa , .ptfab , etc) are read in and their states are concatenated internally.

To read in a given family only select is base member (eg <name>.ptfad ) explicitly and only that remesh family will be read.

Eigenvalue (modal analysis) files

D3PLOT supports output files from modal analyses. They are treated in exactly the same way as transient analyses except that:

Each "state" is a modeshape, and the States Slider moves between these.
Animation works on the currently selected state only, oscillating it through +/- 180 degrees.

Domain Decomposition files from MPP analyses

The MPP version of LS-DYNA can write a pseudo PTF file that shows the domains into which a model has been decomposed for parallel analysis. It contains undeformed geometry only.

This is not a true PTF file and, in particular, each domain is a part that contains elements of all types in its region. Strictly this is illegal: parts can only contain elements of one type, so D3PLOT handles this automatically as follows:

The special file type is diagnosed automatically from its contents
The composite parts of each domain are split into separate solid, beam, shell and thick shell element parts
These are given labels that make them the same colour in D3PLOT's default colouring scheme
Groups of each domain, containing all parts in that domain, are automatically constructed.

In this way the technically illegal domain decomposition file can be processed normally, and the use of groups makes the sketching and (un)blanking of domains very straightforward.
