ReadDyna3D reads the binary plot file "LS930 .PTF" written by LS-DYNA3D, a software package for Nonlinear Dynamic Analysis from Livermore Software Technology Corporation. Attention: Thick shell elements are not supported!
ReadDyna3D is available for COVISE version 4.5 and higher. It's tested on SGI systems (IRIX 6.2, 6.3, 6.4).
SGI only - no LINUX support
|data_path||File Browser||LS-DYNA plot file location (Version LS 930).|
|nodalDataType||Choice||Select the type if additionally nodal results data should be read like either displacements, velocities, or accelerations.|
|elementDataType||Choice||Select the type if additionally element results data should be read like either components of the stress tensor or the plastic strain.|
|component||Choice||Select the component of the stress tensor [Sxx, Syy, Szz, Txy, Tyz, Txz ]. You may also select the pressure (defined as - Tr sigma / 3 , where Tr sigma stands for the trace of the stress tensor) or the Von Mises stress. Only relevant if chosen "stress tensor" as data type of the second data port.|
|Selection||String||Select parts by ID numbers, e.g. "2-5,10-13". The material number of the Finite Elements in the plot file defines the different parts in COVISE.|
|Min_Num_State||Vector||Select the timestep interval. The components of the vector determine the minimum and number of time steps that are read in. The second component is the number of time steps that will be read (without counting the first one). If the first component is 1, the first time step to be read is the first available time step. If it is greater than 1, then the first time step to be read depends on how many time steps have been saved per file.|
|format||Choice||Select the special format of the plot file. In CADFEM format all numbers, characters, etc are written as real numbers. In the original US format they are written as it should be.|
|only geometry||Boolean||If set TRUE only the geometry and topology section are read, i.e. no state data.|
|outputgrid||UnstructuredGrid||The geometry as a set hierarchy of unstructured grids. Notice that the meshes include the displacements.|
|outputdata_1||Vec3||Additional vector data (displacements, velocities, accelerations) per node.|
|outputdata_2||Float||Additional element data (component of stress tensor, plastic strain).|
The above figure shows a map that performs reading the displaced FE meshes together with scalar state data. The following module DomainSurface is applied to generate a surface polygon of the data-set.
The last figure is a snapshot of the renderer. It shows one step of an airbag visualization.
