Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0020] This embodiment provides a method for reading FEM model files in STK.

[0021] figure 1 It is a schematic flowchart of a method for reading FEM model files in STK in an embodiment of the present invention. Such as figure 1 As shown, the method for reading the FEM model file in STK in the embodiment of the present invention mainly includes the steps as follows:

[0022] Step 101, create a blank template file that meets STK format requirements.

[0023] For example, in a preferred embodiment of the present invention, the blank template file meeting the STK format requirements may be: a blank template file in *.mdl format.

[0024] Step 102, extract coordinate information and polygon metadata in a single file with *.fem format from the FEM model...

Abstract

The invention discloses a method for reading FEM model files in STK. The method includes: A. creating a blank template file conforming to the STK format requirements; B. extracting coordinate information and polygon metadata in a single file with *.fem format from the FEM model file; C. creating in a blank template file A simple model of an irregular mesh object is used as a component, and the extracted coordinate information and polygon metadata are written into the simple model of an irregular mesh object; D. Determine whether all *.fem format files in the FEM model file are have been extracted, if yes, go to step E; otherwise, go to step B; E, write the remaining information of the component to form a template file that meets the STK format requirements. By using the method for reading FEM model files in STK provided by the present invention, related operations such as reading and displaying FEM model files can be performed in STK.

Description

technical field [0001] The invention relates to the field of optoelectronic product application technology, in particular to a method for reading FEM model files in STK. Background technique [0002] In the prior art, Satellite Tool Kit STK (Satellite Tool Kit) is developed by AGI Company and is used for three-dimensional simulation and system analysis software. The STK has been widely used in aerospace, intelligence, radar, electronic countermeasures, missile defense and other fields. However, the STK supports a single 3D model format, and can only load and read model files in *.mdl format, so STK has many inconveniences in interacting with other modeling software. [0003] In the simulation system, the finite element model (FEM) is a relatively common model format, and the file of the model is usually a file in *.fem format. However, due to limitations of the STK itself, the STK in the prior art cannot read files in the *.fem format. Therefore, if the STK can be loaded ...
